Heterobimetallic complexes of iron and copper that features a bridging hydride have been synthesized by reactions between cyclopentadienone derived iron(0) tricarbonyl complexes and N-heterocyclic copper(I) hydroxide species. Carbon dioxide released as a byproduct from these reactions. These bimetallic complexes have been characterized by 1H NMR, 13C{1H} NMR, IR, and X-ray crystallography.  When carbon monoxide (1 atm) was introduced to a THF-d8 solution containing a Fe/Cu heterobimetallic complex, regeneration of the starting iron(0) tricarbonyl complex was observed.  Currently, these Fe/Cu heterobimetallic complexes are being tested for homogeneous water-gas shift reaction.
