Mixed-valance copper clusters have been proposed as the intermediates during the catalytic reactions of natural copper-containing enzymes such as multicopper oxidase and nitrous oxide reductase. In our effort to make synthetic models of these mixed-valence copper clusters, we used a group of pyridylamide ligands as the platforms to support the copper centers with different oxidation states. Some interesting Cu(II) complexes, such as a one-dimensional Cu(II) polymer and a hexanuclear Cu(II) metallomacrocycle complex, have been synthesized and characterized by X-ray crystallography, IR, UV-vis and EPR. Currently the mixed-valence copper chemistry of these ligands is under investigation.
