Abstract
The reaction of metal complexes with dioxygen (O-2) generally proceeds in 1:1, 2:1, or 4:1 (metal:O-2) stoichiometry. A discrete, structural ly characterized 3:1 product is presented. This mixed-valence trinucle ar copper cluster, which contains copper in the highly oxidized trival ent oxidation state, exhibits O-2 bond scission and intriguing structu ral, spectroscopic, and redox properties. The relevance of this synthe tic complex to the reduction of O-2 at the trinuclear active sites of multicopper oxidases is discussed.
