摘要： 本文合成了数个以有机磷作桥基配位体的同核钴和异核铁钴原子簇羰基化合物.通过元素分析、IR谱和1H-NMR谱测定,确定三核钴簇合物Co5(CO)9-(μ3-PR)和异核铁钴簇合物Co2Fe(CO)9(μ3-PR)的分子骨架Co3P和Co2FeP具有三角锥构型,而四核钴簇合物Co4(μ-CO)2(CO)8(μ4-PR)2的分子骨架Co4P2为八面体构型.

Abstract: The Tri- and Tctracobalt Cluster compounds Co3(CO)9,(μ3-PR) and Co4(μ-CO)2(CO)8(μ4-PR)2(R = NEt2,OBu-n, NMc2) have been prepared simultaneously from the same initial material RPCl2 and Co2(CO)8. The trigonal pyramidal structure for the molecule-frameworks Co5Pof Co3(CO)5(μ3-PR)and octahedral structure for the molecul-frameworks Co4P2 of Co4(μ-CO)2(CO)8(μ4PR)2 have been deduced from their IR, 1HNMRspcctroscopic data and clement-analysis.The hcteronuclcar cluster compounds Co2Fc(CO)9(μ3-PR)(R = NEt2, Ph) have been synthesized via a metal-exchange reaction from Co5(CO)9(μ3-PR) and Na2[Fe (C0)4]. The molecule-frameworks Co2FePof Co2Fe(CO)9(μ3-PR) also arc trigonal pyramidal structure.
