Syntheses, Spectroscopic Data, and X-ray Diffraction Structures of the Heterometallic RuRe Face-shared Bioctahedral (eta(6)-c...

Thermolysis of the diruthenium compound [(eta(6)-cymene)RuCl2](2) (1) with ClRe(CO)(5) (2) leads to the formation of the new confacial bioctahedral compound (eta(6)-cymene) Ru(mu-Cl)(3)Re(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)(mu-Cl)(4)Mn(H2O)(2) (5). 3 and 5 have been fully characterized in solution and their molecular structures established by X-ray crystallography.
