Crystal structure of the octahedral Cs4[Re6S8Br6]•2H2O cluster complex

The octahedral Cs-4[Re6S8Br6] cluster complex was obtained by the high-temperature (850degreesC) reaction of stoichiometric amounts of elemental substances (metallic rhenium, sulfur, bromine) in molten CsBr. Crystal hydrate of Cs-4[Re6S8Br6].2H(2)O composition was isolated by recrystallization from an aqueous HBr solution. The crystal structure of the hydrate was determined by means of single-crystal X-ray structural analysis. The compound crystallizes in the hexagonal system with space group P6(3)/mcm and unit cell parameters a = 9.762(1) Angstrom, c = 18.763(2) Angstrom, V-cell = 1548.5(3) Angstrom(3), Z = 2, d(calc) = 5.192 g/cm(3).
