摘要：

The clusters [Cu32Se7(SenBu)18(PiPr3)6], [Cu50Se20(SetBu)10(PiPr3)10], [Cu73Se35(SePh)3(PiPr3)21], [Cu140Se70(PEt3)34] and [Cu140Se70(PEt3)36] were prepared from the reactions of CuCl, RSeSiMe3 and Se(SiMe3)2 (R=Ph, nBu or tBu) in the presence of phosphine ligands and their molecular structures were determined. The Se–Bu bond was cleaved more easily than the Se–Ph bond under the reaction conditions studied.
