摘要：
The compound（n-BuN）[WCuS（SCNCH）]was obtained by the reaction of BuNBr,（NH）WS,NaSNCCHand CuCl in CHCN and CHOH.It crystallizes in the monoclinicspace group P2/c with unit cell parameters:a=21.875（5）,b=16.843（4）,c=17.745（5）,β=101.69（6）°,V=6402（6）,Z=4,D=1.718 g·cm.The final R and Rvalues converged to 0.055and 0.060 respectively.The structure consists of two‘butterfly’units[WSCu]linked togetherby two weak Cu—S bonds and two bridging SCNCHligands.Infrared spectra gave charac-teristic absorptions at 495 cmfor W=S and 450,435,412 cmfor W—μ-S.
