摘      要：The compound(n-Bu_4N)_2[W_2Cu_4S_8(S_2CNC_4H_8)_2]was obtained by the reaction of Bu_4NBr, (NH_4)_2WS_4,NaS_2NCC_4H_8 and CuCl in CH_3CN and CH_*** crystallizes in the monoclinic space group P2_1/c with unit cell parameters:a=21.875(5),b=16.843(4),c=17.745(5)(?),β= 101.69(6)°,V=6402(6)(?)~3,Z=4,D_o=1.718 g·cm^(-3).The final R and R_w values converged to 0.055 and 0.060 *** structure consists of two‘butterfly’units[WS_4Cu_2]linked together by two weak Cu—S bonds and two bridging S_2CNC_4H_8 *** spectra gave charac- teristic absorptions at 495 cm^(-1) for W=S and 450,435,412 cm^(-1) for W—μ-S.
