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. Interesting multinuclear Cu(II) complexes, including a one-dimensional Cu(II) polymer, a hexanuclear Cu(II) metallomacrocycle complex and a trinuclear Cu(II) cluster, have been synthesized and characterized by X-ray crystallography, IR, UV-vis and EPR. Currently the study of these ligands with Cu(I) salts is under investigation.
