#196 – update

#196 – update


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


MnCl4 tetrahedra (purple)
TlCl4 tetrahedra (blue)


Also the poster of the Space group list project was updated, which you can download here:


The Space Group List Project as a Poster

The Space group list project ‘230’ – a collection of examples containing at least one crystal structure for all of the 230 space groups – is now available as a synoptical poster (size DIN A0, 84.1 x 118.9 mm):


Feel free to download and share the PDF!

If you print the poster on canvas you may use it also as a special shower curtain 😉
