#196 – update

#196 – update

F23

Tomas, one of our readers of this blog, identified an error concerning the space group list project. As he correctly pointed out, the entry of #196 (F23) was wrong as the coordinate set of the solvent free zink  sulfate clearly shows F-43m symmetry (#216).

I have informed the FIZ Karlsruhe and they will delete this wrong entry in their ICSD database with the next update/release.

So, the new (approved) entry for #196 is:
tetrakis((18-Crown-6)-thallium) tetrachloro-manganese bis(tetrachloro-thallium)
Coordination Characteristics of Divalent Tetrahedral (Td and D2d) Tetrahalometalate Anions of 3d Elements and Solid-State 18C6 Reorientations
N.S. Fender, S.S. Finegan, D. Miller. M. Mitchell, I.A. Kahwa, F.R. Fronczek
Inorg. Chem., 1994, 33 (18), pp 4002–4008
