I saw the structure. So its the zwitterionic tautomer that crystallizes? Makes sense. If so, I'll redo the ChemDraw, perhaps showing an equilibrium. --Smokefoot (talk) 01:28, 14 January 2009 (UTC)[reply]

Apparently so, here's the ref: Acta Cryst. (1996). C52, 1681-1683. I agree with your suggestions, so I'm starting to upload unit cells, coordination polyhedra and extended arrays for polymeric materials. I'm working on YBCO right now - see Commons:Category:Yttrium barium copper oxide.

All the best

Ben, Thanks for the heads up on the Carboxyl group geometry. Your work on wikipedia is impressive. I uploaded the new image to the page Carboxyl.

Thanks for the encouragement as well as the nifty structures. Even if we dont educate the world, we seem to be learning bits ourselves.--Smokefoot (talk) 01:26, 6 March 2009 (UTC)[reply]

I noticed that you changed the formatting for Plumbide slightly, putting the links to 18-crown-6 and en to the sentence after the chemical structure rather than in the chemical structure itself. Why is that? Chlorine Trifluoride (talk) 14:34, 6 March 2009 (UTC)[reply]

For clarity - we don't normally put links inside chemical formulae.

The guideline is at Wikipedia:Manual of Style (chemistry)#Reactions.

What do you think of the info that I added from Greenwood and Earnshaw? Chlorine Trifluoride (talk) 14:12, 8 March 2009 (UTC)[reply]

Very good. Would you like me to add an image from the crystal structure of one of these compounds?

Ben (talk) 14:16, 8 March 2009 (UTC)[reply]

Yeah. I noticed that there are pictures in the book, but I don't know if we can use those. Chlorine Trifluoride (talk) 14:28, 8 March 2009 (UTC)[reply]

Don't worry, I'll make some in 3D from the original data.

Ben (talk) 14:32, 8 March 2009 (UTC)[reply]

Does the image you posted apply to all nonaplumbide anions or just the potassium cation one? Chlorine Trifluoride (talk) 14:08, 9 March 2009 (UTC)[reply]

I don't know. Greenwood & Earnshaw was written before the nonaplumbide ion had been crystallographically investigated, so it does not discuss the structure (other than to say it's unknown, p. 394). Try a review article - I'll keep looking, too, and let you know.

Ben (talk) 16:01, 9 March 2009 (UTC)[reply]

I found "Aspects of anionic framework formation: Clustering of p-block elements". doi:10.1016/S0010-8545(98)00168-4. Chlorine Trifluoride (talk) 15:20, 10 March 2009 (UTC)[reply]

Additionally, can you also do the structure for the pentaplumbide anion? Chlorine Trifluoride (talk) 16:19, 12 March 2009 (UTC)[reply]

No problem. The image is File:Pentaplumbide-anion-from-xtal-3D-balls.png.

Cheers

Hi Ben. I noticed that you have recently uploaded nice structures of cyclic siloxanes substituted with phenyls. They are not used in an article as far as I see. Do you know, if hexaphenylcyclotrisiloxane and octaphenylcyclotetrasiloxane have industrial or commercial applications (i.e. they are produced/used in significant amounts)? --Leyo 17:41, 17 March 2009 (UTC)[reply]

I don't know, really. I just thought they were interesting examples of conformation. I'll have a look in textbooks.

Ben (talk) 19:50, 17 March 2009 (UTC)[reply]

I have not removed galleries from articles, but a gallery from an article. I acknowledge that there really is no problem. I will explain more in depth on Talk:Butane. Happy Wiki'ing! Bobber0001 (talk) 10:32, 18 March 2009 (UTC)[reply]

Sorry about the plural, I thought it was more than one article. No problem though, happy editing :)

Hi, next time please be careful when reverting edits, as you did with User:Ratpole's edit to Gold. One of his/her changes included a valid spelling correction (abandonded -> abandoned), which you also reverted. I've already fixed the problem, but just keep an eye out for this in the future. Thanks!—Tetracube (talk) 22:58, 8 April 2009 (UTC)[reply]

OK, sorry about that. It is difficult, though. Probably easier to just revert the lot then fix abandonded. It all works out in the end.

Thanks

Ben (talk) 11:03, 9 April 2009 (UTC)[reply]

Hi, Ben. Thanks for the encouraging message. I actually got started making the 3D molecules using your tutorial, so in a way you are sort of my mentor. I would love some pointers on where to find the correct geometries for different molecules so that I do not make the mistake I made again. Thanks! Woodenchemist (talk) 16:11, 10 April 2009 (UTC)[reply]

You're doing a great job. I frequently run into trouble trying to make images that turn out to be misleading - but I learn a lot of chemistry along the way!

If you have access to textbooks, journals and search engines like SciFinder, that'll make things much quicker. If not, there's plenty of free information on the web. The basic idea is simple, and is the same as writing text for Wikipedia: you need to provide a reliable source with each image. The places I often get my structural information from are:

• textbooks that show bond lengths and angles, such as Greenwood & Earnshaw
• journal articles - structures often determined by X-ray diffraction, microwave spectroscopy or electron diffraction
• there are two good websites that publish crystal structures electronically: the AMCSD is free but has mostly minerals, whereas the IUCR's journals have all sorts of compounds, but only some of their content is open-access, notably Acta Crystallographica Section E: Structure Reports Online
• the CRC handbook has a useful table of the gas-phase structures of small molecules

It's normally not good to build a 3D structure from the 2D formula given in a Wikipedia article, because there can be important aspects of the molecule's structure (such as its conformation) that might be calculated wrongly by DS Visualizer.

If you'd like me to find and send you any structural information that you're finding hard to track down, or if you'd like any more tips, just drop by!

Cheers

Dear Ben, you were right to revert my edit of TlCl. Indeed, it is CsI-type at room temperature and converts to TlI structure at low-T only. I have put references on TlI structure as ^[1][2].

I can email you these pdfs if you wish.

Regarding ZnO. IMO, the images are redundant because is not the unit cell, but its expanded graphical depiction, i.e. just a cropped version of . The wurtzite unit cell contains only 4 atoms (see, e.g. http://portellen.phycmt.dur.ac.uk/sjc/thesis_mcg/node47.html). Also, for most readers, unit cell does not say much, i.e. one structural picture is sufficient. If you agree, you may wish to revert your edit, but this of no importance.
