Abstract
The redox properties of heterometallic anionic [Os3Fe(μ-H)(CO)13]-, [Os3Co(CO)13]- and neutral Cp*MOs3(CO)10(m-H)(m-Cl) (M = Rh, Ir) clusters were studied by electrochemical methods at a platinum, a glassed carbon and a dropping mercury electrodes in acetonitrile and dichloromethane solutions. It was established that electrochemical transformations of these heterometallic clusters results in the elimination of M-containing (М = Fe, Co, Rh, Ir) fragments and the formation of homometallic trinuclear osmium clusters.
