This is also an interesting entry because space group #93 is as rarely occupied as space group #89 (P422).
Indeed, the ICSD retrieves 0 hits for this space group!
However, there are 6 hits in the CCDC, and for 4 of them also coordinate sets are given.
Example – Tetraphenylarsonium tetrakis(dimethyldithiophosphinato-S,S’)-cerium
