Abstract

The electrochemical redox processes of two high nuclearity osmium carbonyl clusters [(Ph3P)2N2[Os10C(CO) 24]·PPN2 (1) and Os6(CO)18 (6) have been studied by electrochemical in situ FTIR. The five oxidation states of 1, i.e., [Os10C(CO)24]0/1-/2-/3-/4-, have been characterized. There are no significant structural changes for these species. Hence, the ability of this decanuclear cluster to act as an electron reservoir has been demonstrated. The structural rearrangement associated with the two-electron reduction of bicapped tetrahedral 6 to octahedral dianion [Os6(CO)18]2- and [Os6(CO)18]4- tetraanion has also been investigated.
