Syntheses of heterometallic V/Cu/S clusters and structural characterization of（Et4N）2[V2Cu2S4(C5H10dtc)2]

Three kinds of complexes,V2Cu2S4 cubane-like,VS4Cu4 planar and V3S7 triangular dusters areobtained from a reaction system composed of（NH4）3VS4,CuCl,R2dtcNa and PhSNa.A mechanism of theformation of the products is suggested.The title compound is structurally characterized,showing the metaloxidation states of V（IV）+Cu（I）.Also discussed are IR,UV-Vis and NMR spectra,and cyclic voltagrammetryfor the V2Cu2S4 clusters.
