Description
A series of heterobimetallic complexes containing 3-center,2-electron AuâHâCu bonds have been prepared from addition of a parent gold hydride to a bent d10 copper(I) fragment. These highly unusual heterobimetallic complexes represent a missing link in the widely investigated series of neutral and cationic coinage metal hydride complexes containing CuâHâCu and MâHâM+ moieties (M = Cu, Ag). The well-defined heterobimetallic hydride complexes act as pre-catalysts for the selective reduction of CO2 to HCO2Bpin using HBpin as a reductant. Similar results are found with ill-defined Pd / Au and Ni / Au ad-mixtures. In all cases the selectivity of these catalysts for production of a formate equivalent surpasses that of the monomeric components.
