Template:Chembox is permanently protected from editing because it is a heavily used or highly visible template. Substantial changes should first be proposed and discussed here on this page. If the proposal is uncontroversial or has been discussed and is supported by consensus, editors may use {{edit template-protected}} to notify an administrator or template editor to make the requested edit. Usually, any contributor may edit the template's documentation to add usage notes or categories. Any contributor may edit the template's sandbox. Functionality of the template can be checked using test cases.

This is the talk page for discussing improvements to the Chembox template.

This page is for discussion about format, layout, content (parameters), and application howto of the Chemical infoboxes. Discussions older than several months, and now outdated, are archived. Planning and progress of implementation of these infoboxes to the numerous articles is discussed and (where possible) organized in the Chemicals WikiProject, part of the Chemistry WikiProject.

This template was considered for deletion on 2018 November 26. The result of the discussion was "withdrawn".

Implement changes in sandboxes, which allow classes to be applied to images. Snowmanonahoe (talk · contribs · typos) 21:41, 16 May 2024 (UTC)[reply]

On Inverted sugar syrup, ImageFileL1 and ImageFileR1 images probably will need mw-invert like this, however if the files aren't always black and white, probably some other approach is needed (cc: User:Jdlrobson) −ebrahim^talk 19:09, 4 June 2024 (UTC)[reply]

I fixed this some time ago. Use ImageClassL1 and ImageClassR1. Snowmanonahoe (talk · contribs · typos) 19:32, 4 June 2024 (UTC)[reply]

I've been considering trying to apply it to chemistry articles wholesale somehow. I wonder how one would go about analyzing an SVG to determine whether or not the only existing colors are black and/or transparent. Snowmanonahoe (talk · contribs · typos) 19:35, 4 June 2024 (UTC)[reply]

Maybe adding a parameter to the infobox would be a good first step? 🐸 Jdlrobson (talk) 22:40, 4 June 2024 (UTC)[reply]

Yes, I did that as I said in the previous comment. ImageClassL1 and ImageClassR1. Snowmanonahoe (talk · contribs · typos) 23:13, 4 June 2024 (UTC)[reply]

I thought maybe like that change for signature of Infobox person all images can have mw-invert. Another template just spotted today Template:Infobox Chinese on Art name, maybe we need a special temporarily wikiproject or a noticeboard for enlisting and fixing dark mode related issues (cc: User:Snowmanonahoe and User:Jdlrobson) −ebrahim^talk 12:24, 7 June 2024 (UTC)[reply]

We have mw:Talk:Reading/Web/Accessibility for reading but it's not advertised that much. Snowmanonahoe (talk · contribs · typos) 13:43, 7 June 2024 (UTC)[reply]

What about adding a new category e.g. Category:Templates with dark mode issues ? We could subscribe to that and use it to flag dark mode issues? 🐸 Jdlrobson (talk) 15:43, 8 June 2024 (UTC)[reply]

Essentially all chemical-structure diagrams are line-art and most use transparent background. It's nowhere near contained to chembox/drugbox. See for example [1]. DMacks (talk) 16:48, 8 June 2024 (UTC)[reply]

Not sure if this is correct forum to post this. When I try to use some features, such as quadruple bond ($) and square planar (@SP) when editing the SMILES model in chembox of a compound on Wikipedia, it ends up either crashing or not rendering correctly. Anyone knows why this may be the case? AnDeargMor (talk) 12:00, 12 June 2024 (UTC)[reply]

Hi AnDeargMor,

Could you explain what you mean by "crashing", and what kind of "rendering" you mean? Some specific examples would be best. DMacks (talk) 15:03, 12 June 2024 (UTC)[reply]

For instance, when I was trying to indicate square planar structure for Cisplatin by using [NH3][Pt@SP1](Cl)(Cl)[NH3] with notation from the Daylight Chemical Information Systems’ theory manual on SMILES, it instead showed the platinum as a pink atom and the structure stayed tetrahedral. Also, when I was trying to indicate the presence of the quadruple bond in Chromium(II) Acetate using [Cr+2]1234([OH2])$[Cr+2]([OH2])(O[C-](C)O1)(O[C-](C)O2)(O(C)[C-]O3)O(C)[C-]O4, it simply says it can’t load the file when I click on the link to the model AnDeargMor (talk) 16:13, 12 June 2024 (UTC)[reply]

The JSmol tool in the Chembox and Drugbox is hosted by a third party, and is unfortunately limited in its ability to handle metal-complex and several other classes of structures that have special or complicated geometry based on our SMILES strings. And it relies on a fourth party (NCI CACTUS server) for some structures, adding yet another layer of possibly fragile interaction or incomplete support. Wish we had a better way:( DMacks (talk) 17:11, 12 June 2024 (UTC)[reply]

Sounds complex as hell. I’ve also noticed that any SMILES model with Uranium in it will fail to load, is the convoluted hosting also a cause for this? AnDeargMor (talk) 11:33, 13 June 2024 (UTC)[reply]

Depending on font and screen size, the lists of parameter names and explanations may fail to be aligned with each other. Jorge Stolfi (talk) 22:05, 2 July 2024 (UTC)[reply]

Please see discussion at Template talk:Chem molar mass#Non-standard molar mass notation that is about the display of part of the Chembox. DMacks (talk) 04:07, 3 July 2024 (UTC)[reply]
