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.

硫化铋螺二立方烷阳离子的离子热合成

在离子热合成中，硫化铋与螺二立方烷阳离子 (Bi ₇ S ₈ ) ⁵⁺反应，后者结晶为结构复杂的盐。尽管堆垛层错阻碍了所有化合物的完整结构阐明，但各种碱金属阳离子与这些聚阳离子并入，暗示了结构族的存在。
