Synthesis and Characteristics of Heterobinuclear Cu(II)-M(II) (M=Mn,Ni,Cu,Zn) Complexes from New Oxalamide Bridging Macrocyclic Dioxotetraamines Ligand

Cu(Ⅱ)_M(Ⅱ) (M=Mn, Ni, Cu, Zn) heterobinuclear complexes from new oxalamide bridging macrocyclic dioxotetraamines ligand are synthesized. They are characterized by elemental analysis, IR, UV_visible spectra, molar conductivity, thermogravity analysis and room temperature magetic moments. Study shows that there are Cu(Ⅱ)_M(Ⅱ) heterobinuclear complexes with Oxamidgin_bridging structure, Copper(Ⅱ) with a planar environment and M(Ⅱ) with an octahedral environment.The study of room temperature magnet shows that there are weak antiferromagetic interactions between the two metal ions within a molecule.
