| Popis: | Bi2S3 was dissolved in the presence of NaCl in the ionic liquid [BMIm]Cl ⋅ 4AlCl3 (BMIm=1‐n‐butyl‐3‐methylimidazolium) through annealing the mixture at 180 °C. Upon cooling to room temperature, orange, air‐sensitive crystals of Na(Bi7S8)[S(AlCl3)3]2[AlCl4]2 (1) precipitated. X‐ray diffraction on single‐crystals of 1 revealed a triclinic crystal structure that contains (Bi7S8)5+ spiro‐dicubanes, [S(AlCl3)3]2− tetrahedra triples, isolated [AlCl4]− tetrahedra, and sodium cations. In an ionothermal synthesis bismuth sulfide reacted to spiro‐dicubane cations (Bi7S8)5+, which crystallized in a complex structured salt. Diverse alkali metal cations were incorporated alongside these polycations, hinting at the existence of a structure family, despite stacking faults preventing a full structure elucidation of all compounds. |
