Besides the fact that this article is desperately in need of expansion, I'm not sure any of the infobox is right. That structural formula and name appear to be for a completely different compound. Related, maybe, but not the same. -- 2ReinreB2 ( talk) 01:29, 29 March 2016 (UTC)
I looked around. This species has never been isolated. It is referred to in hundreds of papers, many either old-fashioned or just old. It is mentioned as an test for Fe(III) in samples. The spot test for Fe(III), mentioned in some textbooks, involves adding SCN- to Fe(III) solution, but there is no discussion in the two books I consulted of what the species really is. A JACS paper from the 1940's shows that it is a 1:1 complex, probably [Fe(NCS)(H2O)52+ (as depicted). A lot of the present article appears to be intelligent conjecture, probably is overstepping what is known, since the literature is so thin on details.
My proposal is to compress the content and shift it to the article ferric, since it is a test for that oxidation state of iron. But counter proposals are welcome. -- Smokefoot ( talk) 22:42, 6 May 2016 (UTC)
Last week I checked the CSD for Fe-SCN and Fe-NCS species. There are a handful of examples of the former, and hundreds of the latter. No smoking gun, though - i.e. no [Fe(NCS)(H2O)52+. -- Ben ( talk) 23:03, 11 May 2016 (UTC)
If there are organic cations or solvent molecules, they would be, and the CSD is much easier to search by structure. I tried Karlsruhe, too, and got nothing. Do it! Although I'm surprised it hasn't been done already, which makes me think maybe there's more to this species than meets the eye. -- Ben ( talk) 11:33, 12 May 2016 (UTC)
There are more modern education references, including the following: 1998 - ionic strength effect on equilibrium and 2011 - colorimetric determination of K. -- Ben ( talk) 11:38, 15 May 2016 (UTC)
