| Abstract: | 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]2AlCl4]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. |
