摘　　要：通过[PPh4][(mthp S)WS3](mthp=2 methyltetrahydro 2H pyran)和三当量CuBr反应合成了一个新的T型簇合物[PPh4]2[WS4(CuBr)2.6],用单晶X射线衍射方法测定了结构,其二价簇阴离子具有一个由三个铜和一个WS4单元组成的T型WS4Cu3簇结构.Reactions of[(mthp S)WS 3](mthp=2 methyltetrahydro 2H pyran)with three equiv of CuBr in CH 3CN afforded a new T like cluster 2[WS 4(CuBr) 2.6 ](1).The structure of 1 was confirmed by elemental analysis, IR and single crystal X ray diffraction analysis.The structure of either [WS 4(CuBr) 3] 2- or [WS 4(CuBr) 2(CuBr) 0.2 ] 2- dianion in 1 contains a T shaped WCu 3 cluster core in which the tetrahedral WS 4 unit is surrounded by three copper atoms via sulfur bridges.The mean W(1) Cu and W(2) Cu bond lengths are 0.2626 nm and 0.2669 nm, respectively.
