Synthesis, Characterization and Property of Two Kinds of Binuclear Cu(II)-Cu(II) Complexes by Asymmetric Oxamidate-Bridging Ligand

A new oxalamide ligand and its mononuclear complex with Cu(Ⅱ) and two kinds of Cu (Ⅱ)-Cu(Ⅱ) binuclear complexes are synthesized. They are characterized by IR, UV-visible spectra, molar conductivity, thermal property and EPR spectra. Study shows that Cu(Ⅱ)-Cu(Ⅱ) binuclear complexes with asymmetric oxamido_bridging structures.
