Syntheses, Spectroscopic Data, and X-ray Diffraction Structures of the Heterometallic RuRe Face-shared Bioctahedral (η6-cymene)Ru(μ-Cl)3Re(CO)3 and MnRu2 Edge-shared Trioctahedral [fac-ClRu(CO)3]2(μ-Cl)4Mn(H2O)2 Complexes

摘要

Thermolysis of the diruthenium compound [(η6-cymene)RuCl2]2 (1) with ClRe(CO)5 (2) leads to the formation of the new confacial bioctahedral compound (η6-cymene)Ru(μ-Cl)3Re(CO)3 (3) in good yields; the same product has also been isolated when a mixture of 1 and 2 is irradiated with near UV–vis light for an extended period of time. Heating 1 and ClMn(CO)5 (4) does not furnish the corresponding manganese analogue of 3 but rather the trioctahedral halide-bridged product [fac-ClRu(CO)3]2(μ-Cl)4Mn(H2O)2 (5). 3 and 5 have been fully characterized in solution and their molecular structures established by X-ray crystallography.
