The Cube-Shaped Main Group Element Clusters (Bi4S4)4+ and (Bi4Se4)4+ —
Synthesis from Chloroaluminate Melts, Crystal Structures and Vibrational
Spectra. — The compounds (V) containing the cubane-like title cations crystallize in
the tetragonal space group I4 with Z = 2 (single crystal XRD) and are isotypical to the
already known (Bi4Te4)[AlCl 4]4. Besides nearly regular tetrahedral [AlCl4]- ions the
structures contain (Bi4S4)4+ and (Bi 4Se 4)4+ cations which are actually of crystallographic
S4 symmetry but deviate only slightly from the ideal cubic symmetry. — (BECK*, J.;
