This is a subpage for '''image requests''' on [[Wikipedia talk:WikiProject Chemistry|WikiProject Chemistry]].

The aim here is to make bring existing articles alive by the use of interesting images. This can be accomplished by:
* photographs of samples of chemicals to give readers an idea of what they are beyond a one-dimensional text
* photographs of reaction set-ups to see what chemists do
* spectacular chemical reactions or similar, such as those shown on [[Flame test]] and [[atomic carbon]]
* adding illustrative 2D or 3D line images to articles
* Please place all images on the [[Commons:Commons:Upload|Commons]], so other language wikipedias can benefit from your hard work.
* Feel free to add to this list! Also, feel free to jump in and help out!

The diagram is conflating the ideas of the oxygens being anions (vs the iron cationic) with a drawn covalent bond.

*::I'll ask [[User:Materialscientist|Materialscientist]] for a statement. --[[User:Leyo|Leyo]] 14:04, 22 September 2011 (UTC)
Many compounds share the same structure. There are more than a hundred of such classes with easily several dozen (or more) compounds per class. All such drawings are crude approximations, and even the color and radius of atoms is not systematic because different programs have different default settings (which are time consuming or not possible to tweak). Thus yes, ideally we should draw every structure, which will have slightly different atomic radius, color and bond angle, but in absence of those, reusing one structure is Ok, perhaps with a comment on reuse. On pixelation: I have produced dozens of poor quality drawings in my early time on WP (pixelated jpegs with black background). I'm trying to gradually redraw them all. Sometimes pixelation is limited by the program and the black background hides that (and thus swapping black to white in the image makes things only worse).
