Image:Glycine.png and other

Please note that SVG is better format for such images. --EugeneZelenko 16:12, 21 March 2006 (UTC)

But as for SVG vs. PNG, I can't create SVG files from Photoshop Elements which I use, and also, the Wikiproject on Chemistry suggests uploading chemical structures as hi-res PNGs, so that's what I'm doing.
May be these recommendations was written before MediaWiki software added support to SVG. In any case SVG internally converted to PNG before displaying in pages.
You could also use http://inkscape.org. --EugeneZelenko 16:50, 22 March 2006 (UTC)
From my (EugeneZelenko) talk page:
try coreldraw ? it is vectorized.
or try out http://www.uku.fi/~thassine/ghemical/ :-)Schmierer 16:35, 22 March 2006 (UTC)
I don't have CorelDRAW. I downloaded Inkscape, but it requires me to install X11 and I don't have the space for all that on my laptop. Gchemical only runs on Linux, which I don't have either. So I can't upload my images as SVG. Should I not upload any images anymore if I can only make PNGs?
Ben 17:53, 22 March 2006 (UTC)
Strange... Older version of Inkscape installed without problems on my Win98.
Sure, you could upload PNGs, if you could not create SVGs. I just wanted to let you know that SVG is better format and convince you to try other tools. Sorry, if I created too much troubles for you.

Hello. Thanks for putting chemical images in wikipedia. However, your structure of acetyl-CoA has incorrect stereochemistry of the secondary hydroxyl on the pantetheine arm. -Mike

Nonmetal compound

The English Wikipedia doesn't define what is a “nonmetal compound”; so we could think that an imaginative user has made-up this expression. If you know that it has some meaning in chemistry, can you give me its precise definition?

Then, we'll discuss about the Commons category Category:Nonmetal compounds. --Juiced lemon 18:38, 16 December 2006 (UTC)

“A nonmetal compound is any chemical compound containing atoms of a w:nonmetal.”
With such definition, the category Category:Nonmetal compounds is useless. We can use directly Category:Chemical compounds. --Juiced lemon 19:36, 16 December 2006 (UTC)
I reverted your edits because we don't need to clutter up categories with the compounds categories for each element. For example, Category:Metal compounds contains only what is of special interest; so, the right way to find a compound which contains the metal element X is:
Category:Metals>Category:X>Category:X compounds.
You said that your edits were good, but I found some curious categorizations:
You must always check what you do. Don't worry, sometimes, I also make mistakes. --Juiced lemon 20:32, 16 December 2006 (UTC)
Na (en:Sodium) is not a nonmetal element
Cl (en:Chlorine) is not a nonmetal element
Therefore, NaCl is not a nonmetal compound. --Juiced lemon 21:12, 16 December 2006 (UTC)
Have you discovered something about chlorine that the English Wikipedia don't know? In that case, I'll annouce it in the village pump. --Juiced lemon 21:20, 16 December 2006 (UTC)
Sorry, but I refered only to the list of elements in en:Nonmetals which is incomplete. More, en:Periodic table#Standard periodic table and en:Template:PeriodicTablesFooter display Nonmetals as clearly separated from Halogenes and Noble gases.
I found also contradictory sources, like this one: [1]. I'll try to find reliable sources on the subject.
That doesn't change my opinion about Category:Nonmetal compounds. A category which contains near all chemical compounds is useless. --Juiced lemon 23:38, 16 December 2006 (UTC)
The category Category:Nonmetal compounds is for the chemical series, because it's the classification in the English Wikipedia. Your categorization is wrong and useless, so stop your edit war. We can discuss if you stop to revert my edits. --Juiced lemon 00:28, 17 December 2006 (UTC)

Hi Ben,

I just wanted to say that it was really nice to read your polite and considerate posts at Commons:Administrators'_noticeboard#Nonmetal_Compounds. It seems like you got a bit frazzled. It happens to most of us! But it's best to try and remember that our work here is nice, but ultimately still trivial (i.e.: not worth the stress). It's obvious to me that you have given some thought to the topic and for that reason alone, I hope you will not be discouraged from editing. Editors who care are our #1 asset. :) User:Juiced lemon is also an editor who cares, I think, but they are pretty straight-to-the-point and won't tolerate anything that doesn't have good reasoning behind it. These are not so bad things, but can be a bit unnerving at first.

Anyway just wanted to drop and say chin up, no harm no foul, etc, and I look forward to seeing your edits in the future. :) cheers, pfctdayelise (说什么?) 14:34, 18 December 2006 (UTC)

***.elpot.png

Hi Ben, I am a great fan of your beautiful molecular structure pictures. I have impressed by ones with colored decoration like Image:Carbon-monoxide-elpot.png. If some informations about their chemical (and/or physical) meanings are provided, we will able to enjoy them not only by thier cheerful appearance, but also by getting an insight into their property. I guess it may be a surface of the electrostatic potential plane or else, but uncertainly. Could you please tell us about thier details? Regards, --Calvero 14:24, 18 December 2006 (UTC)

Hi JP. The elpot (electrostatic potential) surfaces I occasionally upload are made in Wavefunction's Spartan Student Edition. The surface is equal electron density with an isovalue of 0.050 (not sure what the units are, I'll try to find out from the manual). The electrostatic potential is indicated by colour, but again, I'm not sure of the numerical values that each colour corresponds to. All I know for sure is that red regions are electron rich and blue are electron poor.
I'll let you know the proper numbers as soon as I find them.
Cheers
Ben 18:45, 18 December 2006 (UTC)
Thanks, I got it. --Calvero 14:12, 19 December 2006 (UTC)

Reversions

You make the wrong choice about Commons. The aim of this project is to provide media files to other projects, not to bring informations about encyclopedic subjects, unless this information is useful to find media.

I already said you that halogens and noble gases were NOT nonmetals as a chemical series. The English Wikipedia choosed the classification by chemical series in en:periodic table and in the en:template:PeriodicTablesFooter, and we have not to use different, unsourced and confusing schemes.

I don't care if you are or not an expert in chemistry. We don't use a lot such skills in Commons. --Juiced lemon 18:23, 18 December 2006 (UTC)

The English Wikipedia is the reference for Commons. If you find something wrong in this encyclopedia, go there and correct it. Here, we are NOT writing an encyclopedia. --Juiced lemon 18:37, 18 December 2006 (UTC)

I disagree (Wikipedia is full of incorrect info, I improve it all the time), but it doesn't change the fact. Noble gases and halogens are nonmetals, you just misinterpreted the Wikipedia article.

Ben 21:14, 18 December 2006 (UTC)

I have asked a peer review for the en:Chemical series article in the English Wikipedia. As the categories structure in Commons matches the current contents of this article, please stop to modify this structure until completion of the review. I'll comply with the results of this peer review. --Juiced lemon 13:24, 19 December 2006 (UTC)
That's nonsense. First, the english wikipedia already says in multiple places that halogens are nonmetals. Second, any textbook whatsoever and any chemical dictionary will say the same. Itub 13:35, 19 December 2006 (UTC)

Cool stuff!

I like the chemical images you're uploading. How did you make them? (Just curious).

Do you happen to work on wikibooks by any chance? These images could really come in handy if someone (possibly you?) were to work on an advanced chemistry book :) --SB_Johnny|talk|books 22:48, 16 January 2007 (UTC)

Hi Johnny - thanks! I don't work on any Wikibooks at the moment, but I could. Do you work on chemistry wikibooks? How I make my images is explained fully at w:User:Benjah-bmm27/MakingMolecules. If you want to make you own images, follow that link and ask me for any help you may want.
See you around
Ben 22:57, 16 January 2007 (UTC)
I actually work on a gardening book, but it's kind of cool when there are diagrams like that when I'm doing a page about various garden chemicals (from nitrate to glyphosate). I don't know if anyone's doing much work on the chemistry books these days. --SB_Johnny|talk|books 15:13, 17 January 2007 (UTC)

PNG to SVG

Hey Ben. I'm making an amino-acid poster and your pictures are life-saving. For various reasons I couldn't work with PNG format, and after I saw your discussion page I have some ideas:

  • I was trying to do "Bitmap Tracing" in Inkscape (which uses potrace) but it requires multiple scans and the quality is not so good even after 20 scans.
  • My next shot is Adobe's Streamline. I'll let you know the outcome.
  • If Elements won't let you export to SVG, maybe the complete version of Photoshop may..?
  • Or maybe you can save as *.ai (Illustrator's format), which is also a vector format.

Thanks a bunch, Mintz l 10:26, 20 January 2007 (UTC)

Hi Mintz. I've been through some of these options. The full version of Photoshop doesn't export to SVG. I've downloaded a free 30-day trial of Illustrator. Shall I send you the amino acid images you need in SVG or .ai format?
Cheers
Ben 14:21, 20 January 2007 (UTC)
Hope you guys don't mind me just randomly entering your conversation, but I've been using the free program BKchem for producing SVG chemical diagrams and it's really handy. It runs on Windows, Linux and MacOS, and is Python-based so can probably run on other OSes as well. It doesn't trace PNG files but I've found it quite quick and easy constructing structures from scratch since it's built specifically for that purpose. Bryan Derksen 06:32, 22 February 2007 (UTC)
Oh, and for further editing I recommend use Inkscape. It opens the SVG files produced by BKchem without any problems and has a lot of non-chemical-related editing tools for doing further work with. Also free software. :) Bryan Derksen 06:36, 22 February 2007 (UTC)

Sinigrin

Hey there! I noticed that your image of the structure of Sinigrin (Image:Sinigrin-2D-skeletal.png, Version 20070327192303) featured a cross between the C and the N. I've assumed that this is a mistake, and that it was meant to be a C=N double bond, and corrected the image. If this is wrong, please revert my change and explain on the image description what the C×N means. Thanks. Smurrayinchester 12:47, 28 March 2007 (UTC)

Hi Smurray! The cross was intentional - it means a double bond that could be either cis or trans. See en:Geometric isomerism for details if you haven't come across cis/trans isomers before. When I first saw this crosssed double bond notation, I was confused, but somehow I found out what it meant. I think I asked the author. I'll revert your change if that's OK.

Ben 16:59, 28 March 2007 (UTC)

Alright, thanks. I'd never seen that notation for cis/trans before. Smurrayinchester 10:16, 1 April 2007 (UTC)

Ben, could you please link to a (IUPAC) page or file where the use of this crossed double bond notation is documented? I am interested in learning more about it, but was not able to find such a documentation. Thanks. --Leyo 16:08, 6 January 2010 (UTC)

Here, page 1961 - it says the crossed double bond notation is unnaceptable - the IUPAC way of doing it is to use wavy bonds.
Hope this helps.

Yes, it does. Thanks a lot. --Leyo 18:05, 6 January 2010 (UTC)

Manganese carbonate

Hello, I think there is something wrong in your photograph. Your manganese(II) carbonate is at least partly oxydised to Mn(III). All the other |manganese(II) compounds in the category manganese compounds are pale pink, and this can be rationalised according to the electronic properties of manganese. Federix 08:35, 17 May 2007 (UTC)

You know what? I cam here 3 years later to make exactly the same comment, and see somebody else has. MnCO3 is indeed pale pink. Your sample must be really crappy to look that bad. Could you please fix or remove it? Sbharris (talk) 22:21, 7 July 2010 (UTC)

Thanks for the photographs

Hi Ben,

I actually liked your photographs of chemical compounds. In fact, while you can find descriptions and structures or formulas for many chemicals on the net, photographic representations are quite rare.

Thanks for putting them in the commons here.

(Being a chemist myself who has traded lab work for producing software, your pictures reminded me of former times.)

I noticed you've uploaded one or more images and I thought I should turn your attention to a common error.
Please give some thought to writing a good description of uploaded images. This ensures that they can be used in more than one way. It also helps those that review and improve categories do a better job, which also ensures that images will get used in novel and interesting ways. Thanks, and happy editing! Siebrand 11:27, 25 June 2007 (UTC)


Adding information to your images

Hi Ben, I saw one of your removals of a no source tag on my watch list. I reverted that, because we need explicit own work declarations. Then I started checking your uploads and see why you would do what you did and why it was incorrect. Please start using the template {{information}} to document your images. Source, author, and a licese are mandatory. Simply slapping is not enough. I would advise you to check all your upload and fix this where needed; I have not tagged them all. Thank you for your consideration. Cheers! Siebrand 11:31, 25 June 2007 (UTC)

Hi Siebrand. The reason I've removed no source tags is as follows. The rules state that [the need to explicity state a source] obviously does not apply if the material is first published on the commons and the uploader is the author of the material.
All my images are first published on commons and I am the author and uploader. The {{PD-user}} tag implies I am the author and uploader - why is it necessary to repeat this information?
I hate using {{information}} because it takes so long to fill out individually for each image. If I'm forced to do so, I might not contribute to the commons any more, because it's such a hassle, and unnecessary.
Ben 13:34, 25 June 2007 (UTC)
Hi Ben. A source is always required. Slapping a {{self}} template on a file does not qualify as such. In case a file was created by the uploader, adding 'I made this myself', 'own photo', or 'own work' as text suffices as source. Please understand that Wikimedia Commons is a value added media repository: your contributions, with minimal required information, are welcomed and appreciated. However, if you truly value our project and our goals, please try to add as much value as possible to your contributions. The template {{information}} helps to make the provided descriptions as accessible as possible. Cheers! Siebrand 16:20, 25 June 2007 (UTC)
OK, point taken, but why does the page I linked to say as source is not always required, whereas you say it is? Who am I to believe?
Ben 16:46, 25 June 2007 (UTC)
To be honest, I hadn't checked the page you referred to. I'll go and check now, change and/or comment here if needed. Cheers! Siebrand 17:14, 25 June 2007 (UTC) P.s. thanks for adding the information. I know it's a lot of work.
It's not too much work for the images you list, but for the thousands of images I've uploaded in the past, it'll take ages! Is there a way of automating the process somewhat?
Ben 17:15, 25 June 2007 (UTC)
You could use AutoWikiBrowser to automatically show you pages in an edit screen, provided you have Windows and use Internet Explorer. That would save you a lot of clicking. I could add the information template (empty) with a but to all your uploads, but that wouldn't really help, I guess. I tagged just a few images to show you. What was the saying? Let sleeping dogs lie? If you do a few every day, you might finish eventually ;)
I have made a small clarification to the page you referenced. See here. Cheers! Siebrand 17:19, 25 June 2007 (UTC)

Ben, I just wanted to say thanks for all the chemistry illustrations you've created for various articles. I went to Chemical polarity while creating a link to it for another article I was editing. I was struck by how nice the article looked — largely due to your contribution. Upon visiting your user page, I was then struck by how prolific you’ve been with so many fine-looking illustrations. Contributors of illustrations are the unsung heros of Wikipedia. Illustrations take so much time to create but enhance articles so very much. The “Tireless Contributor” Barnstar above, is specifically for tireless Wikipedians who contribute an especially large body of work. Greg L (my talk]) 19:55, 29 July 2007 (UTC)

Hi DoSiDo. The SVG version is technically accurate, but the font is a little bit small for use in chemboxes, and the dashed bond is wedged, which is non-standard. These are only minor things though, more a matter of style.
Ben 10:15, 14 October 2007 (UTC)
Hi there, I have a comment on drawing an away-from-plain bond. In the 1996 IUPAC recommendation, the preferred was short parallel lines (non-wedged) as mentioned above. However in the newer version, 2006 recommendation, hashed wedged bonds became preferred one. Anyway minor thing, just for a reference. --Calvero 15:53, 15 October 2007 (UTC)
Thanks, Calvero. OK, so keep the wedged bonds but increase the font size a little and you've got yourself a beaut!
Ben 16:59, 15 October 2007 (UTC)
OK. I increased the font. I will replaced the image. There is currently a problem with the Check Usage script. --DoSiDo 00:57, 17 October 2007 (UTC)

Hi, I have a comment on the above picture. The structure of cyclobutane is reported to be non-planar, but somewhat bent. The C-C-C-C dihedral angle is 31° (see JACS 1992, 114, 7684-7, DOI: 10.1021/ja00046a012 for details). So it would be nice to represent in the picture so that the bent structure is more easily recognized. --Calvero 15:13, 19 November 2007 (UTC)

Done, enjoy!

Wikipedia:Featured article candidates/Nicotinamide adenine dinucleotide

Hi there, I was using your Image:NAD-3D-balls.png in this article and some questions and suggestions have been made on the review. Could you add some clarification? Thanks TimVickers 14:49, 17 December 2007 (UTC)

Image:Chloroprene-3D-vdW.png

Please tell what tool you used to make this diagram (and if it's freely downloadable). I have been using Discovery Studio Visualizer to make such diagrams, but the results are not nearly the quality you get in your 3D molecule diagrams (see image:isopropylChloride.png). Please leave your answer at on my talk page. Thanks. Karl Hahn 13:01, 26 December 2007 (UTC)

Much obliged for your help. I just went through all the choices in Edit -> Preferences in DS Visulaizer, and I couldn't find any adjustment for rendering quality. How do I adjust this to "ultra??" Karl Hahn 20:42, 26 December 2007 (UTC)
Found it. Thanks. I feel the same kind of dumb now as when I'm looking for my cellphone and my wife tells me, "It's on the table, right where you're looking at!" I only thought to click the indents under "3D Window", but not "3D Window" itself. :-b Karl Hahn 21:20, 26 December 2007 (UTC)

L-cysteine?

Hi Ben, I have been looking over this your image of cysteine on wikipedia and can not understand why your image is an L-cysteine. I have checked again and again and can not come to the same conclusion. I believe that the image must be that of an R-cysteine. Please check it over.

Thanks Dave

Hi Dave
I've checked the images at en:cysteine and I cannot see a problem. Both 3D models appear to be L-cysteine.
What made you think they're R-cysteine?
Cheers

THF

Hi again. The first model was one I arrived at before I knew how to use the "Clean geometry" feature of DSV. So it was only my own approximation that I had created by piecing together tetrahedral units. The second version was starting from a planar ring and then applying DSV's "Clean geometry" function (with the hydrogens already attached). Once I figured out how to use the CG feature, the first thing I did was apply it to cyclohexane. To my delight, from the planar ring it took it right to the chair config. With a little hand-perturbation to the planar version I was able to get the twist config. And only by using a starting config very close to the boat config was I able to retain the boat after pressing CG. This, of course, parallels the actual stability (or lack thereof wrt the boat) of the three configs, so I was happy at that point that I knew what I was doing. At any rate, I believed then that the CG function would more accurately reproduce 3D structure than my appealing to my own sense of geometry. I have also experimented with DSV's rendering of double-bond geometry by drawing ClHC=C=CClH. This structure has no asymmetric carbons, but is chiral nevertheless. The mental 3D model of an aliphatic carbon that has always worked for me is to imagine the unpaired electrons as the vertices of a tetrahedron, with a single bond being shared vertex, double bond a shared edge, and triple bond a shared face. DSV does show chirality of the example compound above, but is unclear as to the geometrical relationship of the two double bonds (which provide the 90 degree twist that makes this thing chiral). My tetrahedron model does correctly render the twist and illustrates why it must be that way. So that is one criticism I have of DSV. Another (purely technical gripe) is that if I have two molecules displayed, I haven't yet figured out how to rotate one and not the other. I still haven't yet attempted anything to do with coordinated metals, or with peptides, or with crystals. But I'll get to that.

BTW I was unable to access the diagram at http://www.benjamin-mills.com/THF.pdb.

One more question for you. Is there any freely downloadable equivalent to ChemDraw that you know of? I cannot justify spending ₤₤₤ on it as my writing chem material is strictly a hobby. I am experimenting now using InkScape to cut and paste elements from existing chemical diagrams to produce my own, but that is clearly a poor way to do it. Karl Hahn 16:22, 28 December 2007 (UTC)

I learn something new every day. It had never occurred to me until now that THF had more than one conformer. So indeed both versions of the 3D-plot that I uploaded are correct. I can't find anything in my textbooks about THF conformers, so my guess is that the energy hill that separates them is low enough so that the two conformers are not separable (or separable with only great difficulty at low temp -- I imagine some really exotic procedure like recystallizing from liquid hydrogen solution). Karl Hahn 22:57, 28 December 2007 (UTC)

AXE / VSEPR images

Thanks for the great Category:AXE method images. I only know it under the term VSEPR and therefore collected them at this page so that other language wikipedians can find it more easily. They are now used at German Wikipedia: de:VSEPR-Modell. --Matt 13:12, 1 January 2008 (UTC)

PD-chem / PD-self solution

I've given the situation some thought. I still maintain that the images in question are ineligible for copyright, however, I also know the community is generally fine with these images being tagged with {{PD-self}} in place of a PD-ineligible tag. To some, this isn't the best practice, but to most, this is acceptable. Before undertaking the task of having my bot apply {{PD-chem}} to simple chemical structure images, I assumed this was a non-controversial issue—what the community wanted, even. This is why I set the bot to convert tags that weren't PD-ineligible to start with, in addition to those that were. I didn't see any difference and thought it would better to be consistent. Since a few of you have stress concern with my actions, I guess I was wrong. I apologize. I am planning to revert any changes my bot made to your images (also Physchim62's and Edgar181's images along with anyone else who wishes me to do so). Before I do this, I want to make this is what you want and if there's anything else you would like my bot to do. Cheers, Rocket000 15:42, 3 April 2008 (UTC)

Thanks for the message, Rocket. No need to apologize, it's a difficult area. I just wanted the opportunity for everyone, especially the chemists, to discuss what we think the law says, before big changes went ahead. I'll re-PD my images, because some of them could be converted to {{PD-user|Benjah-bmm27}}, but thanks for the offer.
Cheers
Ben 15:52, 3 April 2008 (UTC)
Are you sure? I can have my bot tag them as {{PD-user|Benjah-bmm27}}. And I understand, I jumped the gun on this one. Rocket000 16:46, 3 April 2008 (UTC)

...this? You contributed thousands of chemical structures, you are (re-)categorizing, tidying and so on.

--IngerAlHaosului 17:09, 6 June 2008 (UTC)


"Hi, IngerAlHaosului,

I noticed you've been uploading a few chemical structures lately. Some of your SVGs have minor problems: wonky bond lines and misaligned atom labels (Image:Bentazepam.svg), absence of expicity hydrogen atoms attached to heteroatoms (Image:Azlocillin.svg) and lack of a whitespace border around the image (Image:5-Azacytidine.svg).

You may wish to consult en:Wikipedia:WikiProject Chemistry/Structure drawing for the settings preferred by the chemistry community at Wikipedia; see also de:Wikipedia:Wie erstelle ich Strukturformeln? for German preferences. The German and English Wikipedias are the two most prolific users of chemical structures, so if you want your images to be most useful to the project, you'd do well to conform to their guidelines.

If you need any help or advice on how to make perfect chemical SVGs, contact User:Fvasconcellos, User:NEUROtiker, User:Leyo, User:Slashme or User:Su-no-G.

Thanks for you efforts, both in creating images and in maintaining commons.

Cheers

Ben 12:28, 5 June 2008 (UTC)"

Hi again,
  1. Sorry, just for reference.
  2. Leave a border of 5% of the original image width either side (so a 1000 x 800 px image will have a border of 50 px all the way around, i.e. it will be 1100 x 900 px)
  3. Beware of copying images that do not conform to guidelines, either. Image:Azlocillin.png is one such image - lack of explicit heteroatoms is almost never seen in professional publications, so we shouldn't be doing it. Only User:BorisTM omits them, and I'm not sure even he does it any more.
  4. Cool
Hope this helps,
Looking forward to more of your work
Cheers
Ben 17:36, 6 June 2008 (UTC)
About heteroatoms and similar stuff, i am a metallurgy student not a chemist so if the source png ,jpg, gif, etc are incorrect then the svg i create will be equally incorrect. The reason i started converting chemical structures to svg is because the graphics file itself is relatively easy to convert. I also do electronic diagrams and alphabet images for the same reason, their easier then lets say a insignia. --IngerAlHaosului 10:04, 7 June 2008 (UTC)
In that case it may be better to leave chemistry diagrams to chemists, unless you're sure the image is acceptable.

Disputed chemical diagrams

Hi Ben, I have been going through Category:Disputed_chemical_diagrams and nominating for deletion images that have been there for more than month. I noticed that a couple of yours, Image:Phosphatidylcholine-2D-skeletal.svg and Image:THC-3D-balls.png, are in that category. Do you wish to keep and/or correct either of them? Otherwise they will eventually get deleted. Cheers, Edgar181 (talk) 23:14, 22 July 2008 (UTC)

Hi Ed, thanks for reminding me. The THC image is probably best just renamed to 8-hydroxy THC - shall I reupload under a new name and have the current one deleted?
The phosphatidylcholine one can be deleted - I'm sure someone more biological and better with SVG than me (e.g. User:Fvasconcellos, User:NEUROtiker) can do the honours, if a replacement is required.
Cheers
Ben (talk) 11:25, 23 July 2008 (UTC)
For the THC image it's probably best to reupload the same file with a different name, then tag the old one with {{bad name}} and someone will delete it. For the phosphatidylcholine, just add {{speedydelete}} and specify you're the uploader and that you don't want to keep it. Thanks. Edgar181 (talk) 12:49, 23 July 2008 (UTC)

I'm not sure. Is such a thing possible?
Ben (talk) 21:28, 4 August 2008 (UTC)
yes, the time you save for not having to make the directory tree the second time can be used to write bots to maintain the directory or manually walk through them. Mion (talk) 21:34, 4 August 2008 (UTC)
Isn't it too late now, though, as EN and Commons each have categories that the other does not?
Ben (talk) 21:37, 4 August 2008 (UTC)
The extra categories on commons stay as they are, because they don't exist on EN, only the the directories that exist in EN but not on commons are copied to commons, in the same run interwiki links to the EN cat are attached to keep the connection and shoot the commons cat template in. the result a lot of empty directories, but now bots like siebot can fill the directories. Mion (talk) 21:54, 4 August 2008 (UTC)
Sounds good, but how do you do it? With bots?
Ben (talk) 22:07, 4 August 2008 (UTC)
If commons agrees on it, I think a one way synchronizing of part of the databases tables (we have to make a request if thats possible) would be the quickest, with a bot its also possible but takes longer. but maybe this is discussed long ago and dismissed ? Mion (talk) 22:21, 4 August 2008 (UTC)

By the way, it would be nice if you could make them in this orientation—they're almost always drawn this way in the literature. Best, Fvasconcellos (t·c) 23:16, 12 October 2008 (UTC)
Hi again FV,
I've made a model of ciprofloxacin, in the orientation you linked to. Would you be able to create a new SVG skeletal formula of ciprofloxacin that matches my 3D image? The existing 2D image, Image:Ciprofloxazin.svg, is oriented differently, which will confuse some readers of the article. The molecule is also zwitterionic - I know we tend to ignore this for amino acids and draw the molecule without charges, but it's very difficult to do this with 3D structures since there is no data on the structure of the non-zwitterionic molecule.
Cheers
Ben (talk) 19:55, 14 October 2008 (UTC)
Thanks! I'll whip up a new 2D structure as soon as I can. I'm wondering if I should render it as the zwitterion... I've never seen a structure of ciprofloxacin with formal charges, unlike some other zwitterionic antibiotics (e.g. several cephalosporins). I think I'll just ignore it as usual :) Fvasconcellos (t·c) 12:58, 15 October 2008 (UTC)

Hi Ben. You created this category a while ago. Is it still needed? We have Category:Organoiodides in Category:Organohalogen compounds. --Leyo 23:18, 22 December 2008 (UTC)

Hi Leyo,
I created the category because there are a few organoiodine compounds that are not really iodides, because the iodine is in an oxidation state higher than -1. They're mostly found at Category:Periodinanes. It doesn't really matter if Category:Organoiodine compounds gets deleted, as I think it is really just a parent category for Category:Organoiodides and Category:Periodinanes.

It is after a long absence. Thank you for always making molecule models. I want to ask you a question about ' Edit > Preferences > 3D Window > Materials ' this time. I always use DSV by the setting of the default, but how should be set Materials to make a molecular model like you?--CCoil (talk) 15:03, 17 January 2009 (UTC)

I don't know - I use version 1.5 of DSV, because the more recent versions (e.g. 2.0) have that materials setting you mention.
To make your models a little more shiny, try adjusting the lighting.
Hope this helps!

Ben (talk) 11:34, 15 February 2009 (UTC)
Ok, a picture based on experimental coordinates would be great. How did you create the above picture? AxelBoldt (talk) 18:17, 15 February 2009 (UTC)

I just built a model in Accelrys DS Visualizer (my method is described here) based on the connectivity and stereochemistry of β-D-glucose - http://en.wikipedia.org/w/index.php?title=Cellulose&diff=64200599&oldid=63204747. I then minimised the energy of a short chain using molecular mechanics. I must have made a mistake, or at least drawn the 2D version wrong.

Category:Organozinc compounds

Hi Ben. Can you please have a look at this category? Some of the structures have zinc bond in a liner way, others in an angled one. --Leyo 13:04, 5 March 2009 (UTC)

In the gas phase, they are apparently linear (Acta Chem. Scand. (1982) A36, 159-166) whereas with amine ligands, they go tetrahedral (J. Organomet. Chem. (2005) 690, 3846-3853).
Ben (talk) 14:50, 5 March 2009 (UTC)
In the first paper I read “The valence angle ZnCC is about 114° in both Et2Zn and n-Pr2Zn”. That does not sound like linear for me. Do I misinterpret this sentence? --Leyo 15:09, 5 March 2009 (UTC)
Greenwood & Earnshaw, p. 1221: "ZnR2... are invariably monomeric in solution with linear C-Zn-C coordination of the Zn atom."
The ZnCC in Et2Zn is not the same as the CZnC angle: C1-C2-Zn-C3-C4. ZnCC means Zn-C3-C4 or C1-C2-Zn, whereas CZnC means C2-Zn-C3.
Ben (talk) 15:16, 5 March 2009 (UTC)
OK, I see. Thanks for the explanation. In this case, four structures in Category:Organozinc compounds have an incorrect geometry, haven't they? --Leyo 15:44, 5 March 2009 (UTC)
I think so - they were probably just following the usual zig-zag convention for alkyl chains, and replaced a C with a Zn. Shall we contact the authors?
Ben (talk) 15:53, 5 March 2009 (UTC)
I contacted two of the three authors. The third is not active any more. --Leyo 17:14, 5 March 2009 (UTC)
Ben is right, I was unaware that organozinc compounds were linear across the C-Zn-C bonds and just drew them with alkane-like geometry. I have replaced my two images, but if either of you would like to update or replace them with something more sophisticated, please feel free to do so. Edgar181 (talk) 21:06, 5 March 2009 (UTC)

Those new images are perfect, Ed. I'm making a 3D model of tBu2Zn from X-ray data at the moment.

Ben (talk) 21:36, 5 March 2009 (UTC)

Should I refresh my Image:Ziram.png-pic? --Yikrazuul (talk) 21:46, 5 March 2009 (UTC)
That might be a good idea. According to Acta Cryst. (1966). 21, 536-546, the structure of the complex is this.
Ben (talk) 22:31, 5 March 2009 (UTC)

Category:Organomercury compounds

Should organomercury compounds also all be linear? There are linear and non-linear images in Category:Organomercury compounds. --Leyo 14:10, 6 April 2009 (UTC)

All the organomercury compounds I've seen are linear. There may well be exceptions out there, but I think File:Diethyl mercury.svg, File:Mersalyl.svg, File:Thimerfonate.png and File:Meralluride.png should be investigated - they are probably linear.
I'll keep an eye out for experimental determinations of these structures.
Ben (talk) 14:45, 6 April 2009 (UTC)
HgEt2 calculated to be linear: J. Phys. Chem. B (2004) 108, 8419–8426, J. Organomet. Chem. (1991) 405, 141-147, Organometallics (1985) 4, 1964–1966.
Ben (talk) 15:05, 6 April 2009 (UTC)
Thanks for the fast reply. Are you going to tag the incorrect structures with {{disputed chem}} or do you want me to do so? --Leyo 15:22, 6 April 2009 (UTC)
I'll do it as I check each compound. Thanks, Leyo, for all your hard work on Commons, especially untagging all those "convert to SVG"s.
Ben (talk) 17:59, 6 April 2009 (UTC)
I have recently finished untagging all your images using CatScan.
File:Phenylmercuric borate.png might also be a candidate to look at. --Leyo 14:03, 8 April 2009 (UTC)

Thanks again, Leyo, you've done a great job.

I've searched SciFinder for structural information on the following compounds:

In the absence of any structure determinations from the literature, I assume they are all linearly coordinated at Hg. There was however a structural formula showing non-linear Hg coordination in the following book, which I would guess is just a mistake. Having said that, Greenwood & Earnshaw does give a few examples of tricoordinate Hg, so it's not impossible.

G. W. A. Milne () Drugs: Synonyms & Properties, Ashgate Publishing, p. 1,280 ISBN: 0-566-08228-4.

What do you recommend? Shall I just contact the authors?

Ben (talk) 16:31, 8 April 2009 (UTC)

That might be a good idea. The chemistry project on de-WP shares the opinion that Hg is linearly coordinated (see here if you are able to read German a bit). --Leyo 06:57, 9 April 2009 (UTC) PS. You might be interested in this RfD.

Nice one :) I did GCSE German, so I understood the main points of the discussion. I've contacted Ed, and I'll contact the others soon - gotta get a train now, though,

All the best

Ben (talk) 11:40, 9 April 2009 (UTC)

Hi Ben. If you have any suggestions for the mersalyl structure above, I'd greatly appreciate them. Cheers, Fvasconcellos (t·c) 17:37, 9 April 2009 (UTC)

Hi FV, I looked quite hard on SciFinder last night, but I couldn't find any discussion of the full three-dimensional structure of mersalyl acid or its derivatives (the sodium salt is more common, apparently). The closest I got was this from here.

SciFinder itself thinks the structure is this, which I take to mean this, but SciFinder can be unreliable in this respect.

Ben (talk) 11:58, 10 April 2009 (UTC)

I see a second mistake in the mersalyl structure - there is a water molecule connected to the mercury, but it should be a hydroxy group. Franz --FK1954 (talk) 21:41, 12 April 2009 (UTC)
Perhaps it's best to simply remove the structure for now. I won't redraw it for the time being—I don't do structures without a definitive source anymore :) Thanks a million to you both. Fvasconcellos (t·c) 16:00, 14 April 2009 (UTC)

File:Atomic-orbital-3dyz-3D-phaseless.png

Hi Ben, I just read the German article about orbitals in which several graphs are included. I think there is a mistake in them because they should not depend on the azimutal angle \phi like several do (e.g. Atomic-orbital-3dyz-3D-phaseless.png). The spherical harmonics' dependence on \phi is only e^(i m \phi). If you want to display the shape (Form in the German article) it should in my opinion be the absolute value of the complex Psi-function because that corresponds to the probability to find the electron. And then there is no \phi-dependence. Just for you to classify what I am saying: I'm studying phyiscs in Germany in the 7th semester. Regards Jan

Hi Jan, thanks for your message.
I'm pretty sure the images are correct - see this University of Sheffield website. I know there can be confusion because physics and chemistry use different orbital wavefunctions - both give the same total molecular wavefunction when added. I haven't studied orbitals from a physics perspective, so it might be best to consult your lecturer. You can find the shapes of orbitals used in chemistry in many chemistry textbooks - try Atkins (de or en).

Hi Ben. Can you please address the dispute yourself? Thanks. --Leyo 09:02, 24 March 2009 (UTC)

Perhaps you could add papaverine to your list of compounds to illustrate? I'm sure its crystal structure is floating around somewhere (bad joke). No rush, of course—just thinking this should be replaced with something a bit more polished. Thanks as always, Fvasconcellos (t·c) 13:45, 15 April 2009 (UTC)

No problem - got exams on Friday and Saturday, so after that I'll do it.

Hello, Benjah-bmm27!

Thanks a lot for contributing to the Wikimedia Commons! Here's a tip to make your uploads more useful: Why not add some categories to describe them? This will help more people to find and use them.

Here's how:

1) If you're using the UploadWizard, you can add categories to each file when you describe it. Just click "more options" for the file and add the categories which make sense:

2) You can also pick the file from your list of uploads, edit the file description page, and manually add the category code at the end of the page.

[[Category:Category name]]

For example, if you are uploading a diagram showing the orbits of comets, you add the following code:

[[Category:Astronomical diagrams]]
[[Category:Comets]]

This will make the diagram show up in the categories "Astronomical diagrams" and "Comets".

When picking categories, try to choose a specific category ("Astronomical diagrams") over a generic one ("Illustrations").

Thanks again for your uploads! More information about categorization can be found in Commons:Categories, and don't hesitate to leave a note on the help desk.

Thank you for the structures for hexagonal ammonium fluorosilicate.

How do you think I should get the structures for the trigonal and cubic forms—along with photos that would also be good for Wikimedia Commons? Johnny Mineralogist (talk) 02:45, 25 November 2009 (UTC)

I get structures from a crystallographic database, but it's not freely accessible - I can access it via my university. I've just had a look: the most recent cryptohalite (cubic) structure determination I found is E. O. Schlemper, W. C. Hamilton, J. J. Rush, J. Chem. Phys. (1966) 44, 2499-2505, and for bararite (trigonal) it's E. O. Schlemper, W. C. Hamilton, J. Chem. Phys. (1966) 45, 408-410.
AMCSD has the cubic structure of [NH4]2[SiF6] from the reference above.
Do you mean actual photographs of the bulk substance? Or images of models of the crystal structure? I've made a guide that describes how I make my images, it's here.

Would it be possible to change the shading, or something, so that the picture is easier to understand? I can't figure out which parts are close to the viewer, and which are far away. --HelgeStenstrom (talk) 12:19, 10 March 2010 (UTC)

Thanks for this, I hadn't noticed that message.
Images of this kind are difficult to make, as there's often a trade-off between clearly showing the geometry around each atom (clearer with perspective) and clearly showing the symmetry of the crystal structure (clearer without perspective). I went for symmetry in this case. I can have a go at making a complementary image, although I won't be able to make it look quite the same as the one we're discussing.
I've made a 3D version here.

Actually no, the nitrogen in the product should have 2 hydrogens and be +1 charge (formation of the ammonium-chloride salt by reaction of the neutral amine with HCl). DMacks (talk) 20:07, 21 April 2010 (UTC)
Thanks, DMacks, I've modified the image accordingly.
Ben (talk) 20:21, 21 April 2010 (UTC)

Ben, would you be able to provide a step by step how to make mephedrone? An all out recipe of a sort, with amounts of each substance included. I am aware the synthesis for it is already listed elsewhere on wikipedia, but as for the amounts and thorough explanation of the synthesis process... very little information is available. Cheers!

I don't want to help people to make (soon-to-be-illegal) drugs for four reasons:
  • That's not the purpose of Wikipedia
  • I might get in trouble
  • I don't think recreational drug taking and/or dealing is a particularly good idea
  • If readers want to learn about synthesis and pharmaceutical chemistry, there are much better ways
Having said that, you can read the information I used to draw the scheme: Forensic Sci. Int. (2010) 197, 59–66 or the relevant section of that paper.

Ben,

I work for a company called Eastern Research Group (ERG Inc.), my name is Morty. I am the one who asked the question above for you information. I understand thoroughly what you said to counter my original statement, however, a very small sector of my company has been commissioned this project for the purposes of shutting down/gathering more information concerning this so called "plant food" and we are seeking the help of individuals with knowledge in this area to assist. If you would be able to rethink my proposition and be of assistance not only would you be providing a great service for me personally, but a job offering (part or full time) would be in store for the remainder of the project. Please post back on here if possibly interested, as I do not particularly have time to read through the articles you provided nor do I personally have an adequate degree of any sort for chemistry. If you are interested you can either post your e-mail or let me know and I will post mine. Thanks again Ben. Cheers.

Nitrate Radical

Hello Ben, many thanks for all your work. This atmospheric chemist really appreciates it.

I've been working off and on to improve the pages on en for NOx and the Nitrogen Oxides. The latter page, nitrogen oxides, needs to include the nitrate radical NO3. Although a radical, it is very important in atmospheric chemistry, particularly at night. (NO and NO2 are radicals, anyways; clearly important radicals belong on this page).

Any chance you can make an image of NO3 radical? [For those keeping track, it should have slightly different nuclear geometry than NO3-].

If you make a version of NO3 radical and put it on that page, I'll at least start a stub for NO3. But we should get on it on the 'category' page for completeness.

Thanks! BoulderDuck (talk) 04:22, 15 May 2010 (UTC)

Can do.
Just been reading the latest articles on the geometry and electronic structure of NO3.
What kind of image were you thinking of, a ball-and-stick model?
Ben (talk) 18:52, 15 May 2010 (UTC)
Ben - you did the pictures for the other Nitrogen Oxides on that page. Space filling models, but you'll want to look since they definitely have a common style.

Warfarin crystal structure

Hi. I'm from en.wiki. The ball-and-stick one you've uploaded from crystallography is the cyclic hemiketal tautomer of the standard structure the drug is given as, including the structural representation above it. This is causing some confusion. If you would label your structure as the cyclic hemiketal tautomer of the structure above, I think people could figure out why they aren't perfectly the same. Sbharris (talk) 00:10, 19 June 2010 (UTC)

Why is the drug drawn differently to how it exists in the solid state?
Is is acyclic in solution (and therefore in injections and in vivo)?
I could compute the acyclic structure, perhaps with a semi-empirical method, but this is verging on OR.

Mephedrone metabolism

Hi Ben, would you be able to make a diagram based on figure 3 of this paper showing the proposed scheme for the metabolism of mephedrone? Also, if you can make space filling diagrams, it would be cool to have one of en:Trehalose, I asked on the chemistry request page but no one has done it as far as I can tell. Thanks!

Hello Ben, My name is Rita Neves. I work in Câmara Municipal de Lisboa, that is a Public Organism in Portugal. Actually, we are working on a road book of Biodiversity of Lisbon, for which we are going to produce a panel and a brochure. We found your photos on Wikimedia Commons and liked specially one of them very much, so we would like to know if you could allow us to use your photos, for free, to publish on this project, knowing that the brochure of will be for free distribution to everyone. The photo we are considering to use are the following:

http://commons.wikimedia.org/wiki/File:Alectoris-rufa-with-young.jpg  - Public Domain

The brochure will have four brackets. - Broochura a pocket to take the route - A brochure to present the day of inauguration

- Schedules for species identification
- Panels that will be fixed in the Land

As i said the Free Access will be everything :)

If you are the author and provide us that photo, we will refer your name in the bibliografy and we need to know what´s the name you want on the bibliography? Ben Mills? If it´s possible please respond to ritasoraia2001@hotmail.com or rita.neves@cm-lisboa.pt or here on Wikimedia.

Thank you very much. Our best regards

Hi Rita,
Of course you may use File:Alectoris-rufa-with-young.jpg.
If you would like to refer to me as the author, you can call me Ben Mills, but you don't have to.

Darifenacin

Hey Ben, how's it going?

Seems I only come round when I have a favor to ask :) Anyway, I was wondering whether you could have a look at this Acta Crystallographica paper and whip up a 3D model of darifenacin. I'm reviewing my old structures and will be making an improved version of File:Darifenacin.svg soon, and thought a compound with this sort of conformation (nearly impossible to represent accurately with a 2D structure) could really use a model to make visualization easier. I don't know whether the article gives you the information you need, but thanks in advance!

Hi Leyo,

I don't really have the software to edit SVGs any more. If you'd like to do it or upload a new version of the file yourself, be my guest.

Cheers. --Ben (talk) 19:20, 31 March 2011 (UTC)

cis/trans oleic acid?

Hi Ben, Is there any problem with the way the skeletal figure and the 3D model are dis-similar on the oleic acid page?

Is one of them twisted on the OH end?

Thanks for all of your contributions. Best regards, Mic

Hi Mic, thanks for pointing out this issue.
Both images are actually correct and equally correctly represent the oleic acid molecule, but they depict two different conformations related by rotation about a carbon-carbon single bond. Rotation about single bonds is usually unrestricted and is constantly occurring – molecules like oleic acid are not rigid, they are constant flopping around like a chain being wiggled.
I'll replace the skeletal formula to make the two represenations match more closely.
Cheers,

file:Cefuroxime-2D-skeletal.png

Hey Ben, there is an issue about your structure. According to the literature, cefuroxime should be in the Z-conformation, however, you have drawn the E-conformation. Would you simply flip the methoxy group? Thx and cheers, --Yikrazuul (talk) 17:26, 6 June 2011 (UTC)

Yes, if you show me where it says this in the literature. --Ben (talk) 10:41, 9 June 2011 (UTC)

I've done the research myself and changed the image. Thanks for letting me know. Cheers. --Ben (talk) 12:10, 9 June 2011 (UTC)

Hey Ben, thx for the response, I could refer to German literature, showing this aspect. But actually you have uploaded another version, so I assume that both conformations exist? Cheers, --Yikrazuul (talk) 19:46, 9 June 2011 (UTC)

I uploaded the other version because when I tried to overwrite the original file, it didn't overwrite properly. See en:Talk:Cefuroxime for my findings. In a nutshell, in all the crystal structures I've seen, the OCH3 group is always trans to the heterocyclic ring (furan in cefuroxime, thiazole in ceftizoxime). --Ben (talk) 10:40, 10 June 2011 (UTC)

Hi Benjah-bmm27, I recognized that in the structure above the height of the "L"s is a little bit bigger than the height of the "C"s. This may cause some trouble if the "L"s are misinterpreted as lone pairs. Could you please fix that? Thx --Mabschaaf (talk) 17:51, 19 June 2011 (UTC)

english Wikipidea FP try

Hi Ben,

I quite like your "ribbon" of organofluorines. so much information on so many key molecules in such a small amount of space. I did a bit of modification to it and am now using it in "Fluorine" which I am trying to get the FA at en-WP.

Also, I entered the new ribbon (rotated and a little re-arranged) for a Wiki Featured Picture try. They are a little down on just pictures of molecules, but I think there is a spark of something special in the way we arrange them with the ribbon and all and sooo many key F-C molecules discussed in article.

FYI, they want an SVG. Do you have or can you help? I asked at graphics help and they said to check if you had something.

See: [3], [4], [5].

Hello there,
I don't have a way of making these images as SVGs - sorry. It is possible to re-draw such an image as SVG if you have appropriate software and crazy amounts of spare time, but I think it's a waste of time. Why not just use PNG? Tell the FA people to get over themselves. No molecular graphics software that I know of exports SVG.
Ben (talk) 17:29, 26 July 2011 (UTC)
Hello, it must not SVG, any vector format is sufficient to convert via a small detour to SVG. It is time as promised to delete File:Fluorocarbon-montage rotated-2.svg. Have a nice day. -- πϵρήλιο 02:34, 16 August 2011 (UTC)

Request for molecule diagram

Hi Ben. I am a big fan of your organofluorine strip of molecules.

Could you make me one more molecule in the same style as the strip? Preference would be for en:Trifluralin, but could be any agrichemical that contains fluorine.

This will support me in article work. I will make a ministrip showing the two drugs, the aenesthetic, and the agrichemical. It will sit in my section on drugs and agrichemicals. Can get one of the graphics lab types to help with the layout, but I need the molecule itself.

Help for an article writer? Please?

Jmol? So say!

If you are using Jmol to create the images of the molecular structures, I suggest you mention this in your presentation (profile).

I get here, from an image on Wikipedia, because it wanted to ask you what program you use to create images of the molecular structures. Through their website I discovered that it is the Jmol.

AlexandreMBM (talk) 15:40, 7 June 2012 (UTC)

As far as I remember, I have only ever used Jmol to make two images: File:Propargyl-chloride-MP2-Jmol-3D-balls.png and File:Aristolochic-acid-from-xtal-2007-3D-balls-Jmol.png.

A file that you have uploaded to Wikimedia Commons, File:1,2-dichloroethane-3D-vdW.png, is missing information about where it comes from or who created it, which is needed to verify its copyright status. Please edit the file description and add the missing information, or the file may be deleted.

If you created the content yourself, enter {{own}} as the source. If you did not add a licensing template, you must add one. You may use, for example, {{self|GFDL|cc-by-sa-all}} or {{Cc-zero}} to release certain rights to your work.
