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.
