Abstract

Redox interactions of the carbonyl cluster compounds of iron [M3Fe3C(CO)15]- (M = Co, Rh) and osmium (μ-H)Os3(μ-OH)(CO)10, (μ-H)Os3(μ-OPh)(CO)10 with a mixture of 2,4,6-tripenylpiranyl radical and 3,5-di-tret-butyl-o-benzoquinone has been studied by ESR spectroscopy methods. It was shown that the piranyl radical is able to activate the one-electron processes resulting in active paramagnetic complexes semiquinone radical with the cluster, which transformate giving new compounds. Scheme for these redox reactions has been proposed.
