Triply cyclometalated trinuclear iridium(III) and trinuclear palladium(II) complexes with a tri-mesoionic carbene ligand

Abstract

The first example of a triply cyclometalated homopolynuclear tri-Ir(III) complex with additional carbene donors is presented. Cooperative catalysis and the interplay between homogenous and heterogeneous catalyses are discussed for the tri-Ir(III) complex and a related non-cyclometalated tri-Pd(II) complex.
