@ChemNerd: I have found File:Sodium-hydroxide-crystal-3D-vdW.png, however this file doesn't depict a single NaOH molecule (cation + anion). But we should also take into consideration that sodium hydroxide is a salt-like compound which usually occurs in a large (infinite) 3D mesh out of cations & ions, hence the file I proposed would be a good replacement!

File:Eugenyl oxalate3D.pngEdit

3D model with incorrect geometry + different sizes of atoms. Wostr (talk) 23:19, 13 July 2019 (UTC)

  • Pictogram voting comment.svg Comment This, as with many of this uploader's 3D images, are composites (possibly from uncited third parties) and hand-creations or tweaks using graphical editors rather than using a molecular modeling package to generate a reasonable result of the molecule itself. The result is therefore a mixture of styles, sizes, and other graphical choices. In this case, it was clearly composed of one eugenyl group from one source and a carboxyl from another source, then cloning and mirroring to get the other half of the molecule. The result is total geometric nonsense regardless of the additional poor matching of atom sizes and/or chemical reasonableness of the conformation. The more pretty one makes something that is false, the more dangerous it is because someone might believe it. COM:EDUSE makes a strong statement that it's not for commons to judge the truthfulness of images, but instead it's up to other wikis' editors and site policies about using it, and we keep it if they use it. However, there's established precedent from commons-chemistry and other working groups that really bad nonsense (not just hoaxes and vandalism) is sometimes deletable even if in-use. And editors who continually upload nonsense on commons or conceal underlying sources, after repeated warnings, often get blocked here without second thought. DMacks (talk) 03:41, 14 July 2019 (UTC)
Thanks for the opinion of all. All are right and defend what they think right. But I, as creator of the files, must say that chemically they are correct (some of you said they are false just to delete them, this is not cooperation, this is lack of respect to other works), and I am poor and don't have a graphical software to help me with the structures. So I use a graphical editor to build the structures. As I said, I don't want to be the only owner to create structures in Wikipedia and I'm not hurt if someone substitutes the files I have created with much love. But what I can't agree is the simple deletion because the color does not satisfy the ego of a certain individual. The chemical structures serves as visual effect for the articles created and they enrich our encylopedia. Instead of taking hasty decisions, let us make a cold evalutaion of what is best for all of us in our hearts and not take hasty actions. Let's unite our hearts to make Wikipedia a great encyclopedia.Claudio Pistilli (talk) 12:29, 14 July 2019 (UTC)

File:Sodium deoxycholate3D.pngEdit

Ball-and-stick model of a salt with covalently bonded sodium cation (BTW why draw such model for salt instead of a crystal structure etc., since such model is fundamentally incorrect, as it cannot exist in reality?). Wostr (talk) 13:48, 13 July 2019 (UTC)

  • Symbol keep vote.svg Keep Original author has uploaded a corrected version with transparent background, ionic structure & improved quality. We should keep the file! Chem Sim 2001 (disc) 16:06, 13 July 2019 (UTC)
The major problem has been solved. The question remains is depicting a salt as an anion+cation in 3D model correct? This is a convention used in graphical representation of structures, not in 3D models. Until recently, we had crystal structures of salts, not simple anion+cation unrealistic models. I won't oppose keeping this file now, but this is the question we should answer, because we have more and more poor models like this one, which are misleading for readers. Wostr (talk) 16:58, 13 July 2019 (UTC)
@Wostr: I completely agree with you in this point. Generally, salt compounds are always ionic and have a large (infinite) 3D mesh out of corresponding cations & anions. (@Claudio Pistilli: Please take this into consideration when creating a 3d ball-and-stick model, sometimes it's better to visualize the compound with a crystal structure such as File:NaCl polyhedra.png. Chem Sim 2001 (disc) 17:24, 13 July 2019 (UTC)
Thank you for you opinions. I agree that the crystal structure is important to show the aggregation state of matter, but when I need to make a single reaction I need the molecule alone, and I miss inorganic files of singles molecules in Commons. Don't you agree?Claudio Pistilli (talk) 10:25, 14 July 2019 (UTC)
No, I don't know why anybody would want to show a reaction using molecules instead of chemical structures (is it an encyclopaedia or a reading book for children?), but that's a problem of your local wiki. The problem here is simple: you've uploaded a lot of files that are not chemically correct — some readers will know it, but most won't, hence you're doing more harm than good.

Poor quality of the "OH" group. It has an opaque background (vs rest of image being transparent)--same problem as Commons:Deletion requests/File:Ethyl cinnamate.svg. The two letters also render inconsistently (and sometimes poorly) at different sizes and mediawiki contexts (sometimes the letters touch/overlap). Category:Butan-1-ol has lots of replacements, including various color-codings, orientations, and levels of detail. DMacks (talk) 05:21, 13 July 2019 (UTC)

  • Symbol delete vote.svg Delete per nomination & reasoning of DMacks. I would suggest File:1-Butanol.svg as appropriate replacement, since the structure has the same orientation & also a highlighted (blue coloured) "OH" group. Chem Sim 2001 (disc) 11:39, 16 July 2019 (UTC)

Deleted: per nomination. --Leyo 10:20, 19 July 2019 (UTC)

File:Bornylacetate.svgEdit

Long-tagged as having ambiguous stereochemistry. It's true...depending if the meaning is for the O on the ring to be distinctly up vs down gives two didfferent chemicals, one of which is not called "bornyl acetate". Category:Bornyl acetate has multiple options (including SVG and high-quality PNG) that have well-defined geometry at this location. DMacks (talk) 05:17, 13 July 2019 (UTC)

File:Schablone Logarex 25525-S, Chemie III.jpgEdit

The current image at this file is apparently an edited version (by User:Zinnmann) of the original (by User:Tzaph) uploaded here, and is tagged for hist-split. However, I think the original is inferior and is not worth keeping (once the image desc is updated to note the details of the latter editor's change vs original). If I were to split it, I would DR the original. So I'm just jumping up to confirm that we don't need to keep the original as a directly usable image (and hence offload it to a separate filename). DMacks (talk) 05:00, 22 June 2019 (UTC)

Likewise the original version at File:Schablone Logarex 25524-S, Chemie II.jpg vs its edit at that same filename. DMacks (talk) 05:04, 22 June 2019 (UTC)

  • Symbol delete vote.svg Delete the original as inferior, and trout the insistent upload warrior.   — Jeff G. please ping or talk to me 05:18, 22 June 2019 (UTC)
  • Certainly, deletion would have advantages. On the one hand, the faulty retouching would not be so easy to recognize and on the other hand, hardly anyone could eliminate this error. What could be more in the sense of the last editor? He would be the only one who benefits from this dubious action, but to the detriment of Wikipedia. MagentaGreen (talk) 07:34, 23 June 2019 (UTC)
I don't insist on my retouched version. Just revert it. --Zinnmann (talk) 12:01, 3 July 2019 (UTC)

Categories for discussionEdit

Category:SVG sterolsEdit

Also two subcats: Category:SVG cholesterol synthesis + Category:SVG cholesterol

Similar situation to Commons:Categories for discussion/2017/11/Category:SVG pharmacologic agents + Commons_talk:WikiProject_Chemistry#SVG_categories. I see no reason for creating categories for SVG chemical structures only. Wostr (talk) 17:51, 13 July 2019 (UTC)

  •   Delete for the reasons stated. --Leyo 12:55, 17 July 2019 (UTC)
  •   Delete the corresponding ones, merge as many as possible. --Allforrous (talk) 23:08, 18 July 2019 (UTC)
  •   Delete per nomination! Chem Sim 2001 (disc) 10:11, 20 July 2019 (UTC)

Category:Methylene groupsEdit

Category for methylene groups containing a subcategory for methylene group (methanediyl group) and for files that are not methylene groups. Imo it's incorrect, according to IUPAC rules there is only one methylene group (and there is a category for this group already) and I don't know what else can be added to this cat. Wostr (talk) 23:11, 16 November 2018 (UTC) PS Probably Category:Methanediyl group should be renamed to Category:Methylene group and Category:Methylene groups may be switched to redirect. Wostr (talk) 23:13, 16 November 2018 (UTC)

@Grasso Luigi: As the creator of the category it would be good to hear your opinion on the suggestions above. --Leyo 11:21, 3 December 2018 (UTC)
