摘要
The title compound has been synthesized by the reaction of(NH4)3VS4, CuBr and NMe4Br in pyridine and its structure was determined by singlecrystal X-ray diffraction. Crystallographic data: C40H40Br3Cu6N8S4V, M4= 1432. 95,orthorhombic space group Fdd2, a= 29. 9519 (2), b=13. 4719 (2), c= 25. 8612 (4)A, V= 10435. 2 (4), Z= 8, Dc= 1.824 g/cm3, F(000)= 5616,μ(MoKa) =50.64 cm-1, the final R =0.091 and wR =0. 206 for those 3401 unique reflectionshaving . The crystal structure determination shows that the cluster consists of a tetrahedral VS4 core encapsulated by a distorted octahedral array of six copperatoms which have two different coordination geometries, trigonal and tetrahedral.
