Photochemical and/or thermal reactions ofCp*Rh(H)2(SiEt3)2 (Cp*= 
5-C5Me5) withthedimeric metal complexes [CpNi(CO)]2 (Cp =5-C5H5),[CpCo(NO)]2,[CpRu(CO)2]2, and[CpFe(CO)2]2 yielded the trinuclear complexes(Cp*Rh)(CpNi)2(CO)2 (3),(Cp*Rh)(CpCo)2(NO)2(4),(Cp*Rh)(CpM)2(CO)4 (5a, M= Ru; 5b, M = Fe), respectively, while the reaction with[CpMo(CO)2]2 gave the tetranuclear unsaturatedcomplex(Cp*Rh)2(CpMo)2(CO)4(6) in good tomoderate yields. Similarly,[Cp*Ru]2(
-H)4 reacted with[CpNi(CO)]2, CpCo(CO)2, and[CpFe(CO)2]2 to give tetrahedral(Cp*Ru)2(CpNi)2(CO)2(7), triangular(Cp*Ru)2(CpCo)(CO)4(8),and tetrahedral(Cp*Ru)2(CpFe)2(CO)4(9) complexes, respectively. The mixed-metalclusters3, 4, 5a, and6-9 have been structurally characterized bysingle-crystal X-ray diffraction.
