[edit] Organization

This article contains much material that isn't about gadolinium(III) chloride at all, but about the Gd(III) ion and its chelates. I'm going to start an article Gadolinium(III) chelate for all the MRI stuff. —Keenan Pepper 21:46, 17 July 2006 (UTC)

The problem is that the lanthanide halides generally have virtually no chemistry in their own right. It's a bit like writing about the chemistry of Na+ under NaCl. The halides just fall off in soln. Regarding your idea, I recommend an alternative tactic - start a subsection in the MRI site on Gd chelate complexes. Otherwise every darned metal ion is going to require a section on their chelates, which would gut most articles. Or, perhaps more collegially, why not pose the problme in the Chemistry talk site so that WE-Chem experts can kick around ideas. One of the WE-Chem experts is a lanthanide enthusiast. --Smokefoot 22:12, 17 July 2006 (UTC)

"In the MRI site"? What does that mean? Also, what makes you say "every darned metal ion is going to require a section on their chelates"? Just because we have an article on some very notable chelates, doesn't mean we have to create articles about a whole bunch of non-notable chelates. —Keenan Pepper 22:38, 17 July 2006 (UTC)

Thanks for bringing this up. I haven't come to look at anything in the Wikipedia linking paramagnetism and NMR, which is similar to this. I think it is mainly Gd(III) compounds that are used as paramagnetic shift reagent and as MRI contrast agent. (funny, both links don't even exist, not sure if I named the second one correct, though). As Smokefoot is suggesting, that might be a better place for the information, and then collaps the section on this page to links to these pages ('main article bladibla'), and some general info why especially Gd. I don't think writing a chelate page for Gd is a good idea, first, all those lanthanides do is chelate (well, metal ions in general like chelation), and it would indeed give rise to many other similar pages for other elements. All of them at least stating the EDTA complex. --Dirk Beetstra ^{T C} 22:30, 17 July 2006 (UTC)

Again, why would it "give rise to many other similar pages"? I don't follow that reasoning. However, I agree MRI contrast agent might be a better place for the article I'm writing. —Keenan Pepper 22:38, 17 July 2006 (UTC)

Anyway, let's continue this conversation at Wikipedia talk:WikiProject Chemistry#Organization of articles about chelates. —Keenan Pepper 22:42, 17 July 2006 (UTC)
