摘　　要：碳硼烷双膦配体L1分别与三苯基膦氯化镍(NiCl2(PPh3)2)和1,5-环辛二烯氯化铱(IrCl(COD))在空气中反应生成含巢式碳硼烷膦氧配体的镍、铱化合物1和2。本文对此两个化合物进行了核磁、质谱、红外及单晶衍射等表征。化合物1中溶剂分子氯仿与主体结构存在着常见的Cl…H氢键作用和较少见的CH…π作用,化合物2是首例以膦氧配体形成的Ir(Ⅰ)配合物,同时由于金属的差别导致了碳硼烷双膦配体被氧化程度的不同形成了新颖的碳硼烷[P,O]和[O,O]配体。The reactions of o-carborane [P,P] ligand L1 with NiC12（PPh3）2 and [IrCI（COD）]2 under an open atmosphere lead to two nido-carborane species 1 and 2 containing [O,P] or [0,0] ligands. All these complexes have been characterized by NMR, MS, IR and X-ray diffraction analyses. Complex 1 with solvent CHC13 formed the normal CI...H interaction and novel CH--.Tr interaction. Complex 2 is the first Ir（I） compound containing [0, P] o-carborane ligand. However, due to the difference of metal （Ni and Ir）, the [P,P] ligand L1 was oxizided to novel [P,O] ligand and [0,0] ligand, respectively. CCDC： 927419, 1; 927420, 2.
