By reaction of elemental bismuth, sulfur, bismuth(III) chloride and gallium(III) chloride in the ionic liquid (BMIm)Cl (BMIm: 1-butyl-3-methylimidazolium), Bi(3)GaS(5)Ga(3)Cl(10)GaCl(4)·S(8) is obtained as red transparent crystals. According to X-ray structure analysis based on single crystals, the title compound crystallizes with triclinic lattice symmetry and is composed of heterocubane-type Bi(3)GaS(5) cations, trimeric star-shaped Ga(3)Cl(10) anions with three (GaCl(4)) tetrahedra sharing a single central chlorine atom, monomeric GaCl(4) tetrahedra and neutral, crown-shaped S(8)-rings. Here, the heterocubane Bi(3)GaS(5) as well as the star-shaped Ga(3)Cl(10) are observed as building units for the first time. Bi(3)GaS(5)Ga(3)Cl(10)GaCl(4)·S(8) is further characterized by X-ray powder diffraction as well as by thermogravimetry/differential thermal analysis.
通过在离子液体 (BMIm)Cl（BMIm：1-丁基-3-甲基咪唑）中反应元素铋、硫、三氯化铋和三氯化镓，得到了红色透明晶体Bi(3)GaS(5)Ga(3)Cl(10)GaCl(4)·S(8)。根据基于单晶的 X 射线结构分析，标题化合物具有三斜晶格对称性，由异核立方烷型Bi(3)GaS(5)阳离子、具有三个 (GaCl(4))四面体共享单个中心氯原子的三聚体星形Ga(3)Cl(10)阴离子、单体GaCl(4)四面体和中性冠状 S(8)-环组成。在这里，异核立方烷Bi(3)GaS(5)和星形Ga(3)Cl(10)首次被观察到作为构建单元。Bi(3)GaS(5)Ga(3)Cl(10)GaCl(4)·S(8)还通过 X 射线粉末衍射以及热重/差示热分析进行了表征。
