Аннотация: The redox properties of binuclear heterometallic complexes Cp(CO)(2)MnPt(mu-C-1=(CHPh)-H-2)(L)(L') [L = L' = PPh3 (1); L = PPh2H; L' = PPh3 (2); L = CO, L' = PPh3 (3); L = L' = P(OPri)(3) (4); L = PPh2H; L' = P(OPri)(3) (5); L = CO, L' = P(OPri)(3) (6)] were studied by electrochemical methods at platinum, glassed carbon and dropping mercury electrodes in acetonitrile. Electrochemical behavior of the complexes were shown to depend on the nature of L, L' ligands at the platinum atom. It was established that one-electron oxidation of 1, 2, 4, 5 results in a cleavage of the Mn-Pt and the Pt-C-1 bonds to give mononuclear phenylvinylidene complex Cp(CO)(2)Mn=C=CHPh (7) and [PtLL'] fragments. The quasi-reversible one-electron oxidation of 3 and 6 is indicating their stronger electrochemical stability in redox-reaction compare to 1, 2, 4, 5.
