[Bi3GaS5]2[Ga3Cl10]2[GaCl4]2·S8 containing heterocubane-type [Bi3GaS5]2+, star-shaped [Ga3Cl10], monomeric [GaCl4] and crown-like S8

Abstract

By reaction of elemental bismuth, sulfur, bismuth(III) chloride and gallium(III) chloride in the ionic liquid (BMIm)Cl (BMIm: 1-butyl-3-methylimidazolium), [Bi3GaS5]2[Ga3Cl10]2[GaCl4]2·S8 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 [Bi3GaS5]2+ cations, trimeric star-shaped [Ga3Cl10] anions with three (GaCl4) tetrahedra sharing a single central chlorine atom, monomeric [GaCl4] tetrahedra and neutral, crown-shaped S8-rings. Here, the heterocubane [Bi3GaS5]2+ as well as the star-shaped [Ga3Cl10] are observed as building units for the first time. [Bi3GaS5]2[Ga3Cl10]2[GaCl4]2·S8 is further characterized by X-ray powder diffraction as well as by thermogravimetry/differential thermal analysis.
