N2 - Photochemical and/or thermal reactions of Cp*Rh(H)2(SiEt3)2 (Cp* = η5-C5Me5) with the dimeric metal complexes [CpNi(CO)]2 (Cp = η5-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 unsaturated complex (Cp*Rh)2(CpMo)2(CO)4 (6) in good to moderate yields. Similarly, [Cp*Ru]2(μ-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-metal clusters 3, 4, 5a, and 6-9 have been structurally characterized by single-crystal X-ray diffraction.
