Designing coordination complexes for multi-electron chemical transformations such as the reduction of nitrogen and carbon dioxide is a major research focus of the Heyduk lab. Towards this end, we use redox-active tridentate ligands such as the N,N-bis(2-hydroxy-3,5-di-tert-butylphenyl)amine (ONO) as electron reservoirs in the synthesis of new coordination complexes. A new strategy that is emerging in the lab is to design and synthesize bimetallic coordination complexes supported by redox-active ligands so that the two metals can work in conjunction with the redox-active ligand to facilitate multi-electron reactivity. This talk will present the synthesis and characterization of a unique heterobimetallic complex of iron and zinc, Fe(ONO)2Zn(ONO), which comprises an octahedral Fe(ONO)22– fragment bound to a five-coordinate zinc(II) center.
