Your molecular model imagesEdit

Hi CCoil,

Thanks very much for you recent contributions. I have two suggestions:


1. Avoid duplication

I've noticed that some of the images you've uploaded are extremely similar to ones that already exist. For example your image Image:Nitrobenzene-balls.png is almost identical to one I made 18 months beforehand, Image:Nitrobenzene-3D-balls.png. It'd be a much better use of your time and effort to make images for molecules that do not already have a good one. I suggest using the Commons search box or Mayflower to check that suitable images do not exist before you decide to make a new one.

Here's a table of images that you didn't need to make:

Existing image Your duplicate
Image:Orthoperiodic-acid-3D-vdW.png Image:Orthoeriodic-acid-CPK.png
Image:Hypoiodous-acid-3D-vdW.png Image:Hypoiodous-acid-CPK.png
Image:Periodic-acid-3D-vdW.png Image:Metaperiodic-acid-CPK.png
Image:Cumene-hydroperoxide-3D-balls.png Image:Cumene-hydroperoxide-balls.png
Image:Oxalyl-chloride-3D-vdW.png Image:Oxalyl-chloride-CPK.png
Image:Perchloric-acid-3D-vdW.png Image:Perchloric-acid-CPK.png
Image:Silicon-tetrachloride-3D-vdW.png Image:Silicon-tetrachloride-CPK.png
Image:Hydrogen-cyanide-3D-vdW.png Image:Hydrogen cyanide.png

One image that was worth updating was my image Image:Oxaliplatin-3D-balls.png. Your Image:Oxaliplatin-balls.png is clearer, so this upload was very useful. The images in the table above, though, seem to be almost identical.


2. Make sure your structures are correct

I've made plenty of mistakes myself in this area - often, the structures of molecules or compounds are not what you might expect. A few of your images seem to contain mistakes in structure. For example, your image Image:Silver-tetrafluoroborate-3D-vdW.png is not right. AgBF4 is not a molecule, it's an ionic crystalline solid, containing tetrahedral [BF4] anions and Ag+ cations. See this article for details on the structure. The other image that needs fixing is Image:Tetrafluoroboric-acid-3D-vdW.png - see en:Fluoroboric acid - pure HBF4 is unknown, the acid is just an aqueous solution of [H3O]+ and [BF4] ions.


I hope these suggestions are helpful, and I look forward to more of your work. There are so many compounds that exist, and the more high-quality images we have to help people understand them, the better. Your work is really valuable to Commons and the Wikipedias that use it.

See you around,

Cheers

Ben (talk) 11:38, 9 October 2008 (UTC)

Hi Ben. Thank you for suggestion.
I intend to take two suggestion willingly. I think that I had to be careful a little more. I intend to give my duplication image a deletion request. It is the second suggestion next, about the structure of the material, where do you find it? Can I find it in a free site?
I am sorry in a short sentence. It is difficult for me to make an good English sentence.
I support that you make a better image.
See you.
--CCoil (talk) 14:28, 9 October 2008 (UTC)

Hi CCoil,

You may request deletion of some of these images if you wish, but there's nothing wrong with them per se, they just have nearly-identical twins! I just wanted to save you some trouble and direct your talents to where they are most needed.

Don't worry about your English, either, it's fine - I understood what you wrote easily. Your English is much better than my French or German is.

As for structural information, the place to look depends on the type of compound you want to draw. For minerals and simple crystalline inorganic compounds like binary halides and oxides, a good first port of call is The American Mineralogist Crystal Structure Database. For discrete molecules try 3DChem.

I personally find some structures directly from papers on X-ray or electron diffraction or rotational (microwave) spectroscopy. You'll need access to journals to get this information, and you'll need to understand the data to convert it into a model, so it might be easier to stick to the websites above.

Good luck

Ben (talk) 19:40, 9 October 2008 (UTC)

Hi Ben.
Thank you for introducing an interesting site. Thank you for praising it about my English. I want to make a lot more more molecule models.
About a molecule model, may I make a Ball-and-stick model same as the CPK model whom you have already made? I think that the molecule model that I can make decreased recently. Had better I make the molecule model of medical supplies?
Thanks again
--CCoil (talk) 23:46, 9 October 2008 (UTC)

Hi Ccoil,

You may, of course, make ball-and-stick models of molecules if only a CPK model already exists.

What do you mean about medical supplies? You can make models of any molecules you choose.

Best wishes,

Ben (talk) 19:53, 12 October 2008 (UTC)

Tip: Categorizing imagesEdit

Hello, CCoil!

Tip: Add categories to your images

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:

Uploadwizard-categories.png

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"). Pro-tip: The CommonSense tool can help you find the best category for your image.

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.

Nice work!Edit

Hi CCoil,

I've just seen your recent images of the crystal structures of mercury and zinc halides:

Very nice! I'm really glad you've found out how to depict the structures of polymeric materials.

Would you be able to add references to these images, such as a link to an article? That would really helpful so people know where the information came from and can check it.

I now do this with my images. For example, I made File:Potassium-tetrachlorogallate-xtal-3D-balls.png using a CIF from Acta Cryst. (2003). E59, i70-i71. I find the references useful if someone thinks one of my images has a mistake - I can check the original document and see if I was right or wrong.

Best wishes,

Ben (talk) 21:25, 15 March 2009 (UTC)

Thank you very much!
This is because you taught me.
I added quotation to each image. Should such a quotation increase it to all images?
I uploaded the image of the File:Mercury(II)-fluoride-xtal-3D-vdW.png again. (File:Mercury(II)-fluoride-xtal-3D-sticks.png)
--CCoil (talk) 09:01, 16 March 2009 (UTC)

That's brilliant. It would be very good to have a reference for each image, so if you're able to provide references, please do so - people really appreciate it. There may also come a time when chemical structure images will require a reference, although this is not the case at present.

You can also make your images shiny by adjusting the lighting settings: http://www.benjamin-mills.com/DS-lighting.png.

Keep up the great contributions!

File:Zinc-chloride-3D-vdW.pngEdit

Hi CCoil. I like your crystall structure images. Could you additionally draw a ball and stick image of zinc chloride, showing the unit cell? In de.wikipedia, we generally prefer to use images with unit cells (or if appropriate a larger part of the crystal structure; see here). --Leyo 10:17, 4 April 2009 (UTC)

A version (File:Kristallstruktur Zinkchlorid.png) is now available. Sorry for disturbing. --Leyo 13:23, 4 April 2009 (UTC)

File:AuBr.pngEdit

Hi CCoil,

I uploaded a version of the P42/ncm phase of AuBr today, without realizing you had pictures of what is supposed to be isostructural: AuI. However I do not understand your pics that well and wonder if there is no error in the choice of origin of the space group. There are two choices and if you take the wrong one you get a strange structure.

Greetings

Jcwf (talk) 04:26, 25 November 2009 (UTC)

Hi, Jcwf.
The original data which I used so that I make an image are [1][2]. Space group of these data is P42/ncm, and space group of Z Krist. (1959). 112, 80-87 is P42/ncm, too. Therefore I think that structure of AuBr is different from structure of AuI.--CCoil (talk) 11:33, 27 November 2009 (UTC)
Hi: I downloaded your cif file and put it back into Atoms. It produces the picture that you have uploaded here. Then I changed the space group from P42/ncm:1 to P42/ncm:2, the only difference being a different choice of origin. So, sorry, but your picture is wrong, because then the structure is the same as for P-AuBr, as it should be and is also stated explicitly in Wiel Janssen's ad Gerrit Wiegers' paper. No my name is not on that paper, but it is on the AuCl one because I grew those crystals: I was the undergruadate, Wiel the grad student and Gerrit our mentor at the time

Jcwf (talk) 18:56, 30 November 2009 (UTC)
