摘　　要：合成了一种新型草酰胺配体和铜单核配合物 ,并以铜单核配合物为母体合成了Cu(Ⅱ ) -Co(Ⅱ )异双核配合物 .以元素分析、红外光谱、摩尔电导、热重分析和室温磁矩对新合成配合物进行了表征 .经研究推定 ,新合成异双核配合物具有草酰胺桥联结构 ,Cu(Ⅱ )和Co(Ⅱ )A new oxalamide ligand and its mononuclear complex with Cu(Ⅱ) and Cu(Ⅱ)-Co(Ⅱ) heterobinuclear complex are synthesized. They are characterized by elemental analysis, IR, UV-visible spectra, molar conductivity, thermogravimetry analysis and room temperature magnetic moments. Studies show Cu(Ⅱ)-Co(Ⅱ) heterobinuclear complex with oxamido-bridging structure, copper(Ⅱ) with a planar environment and cobalt(Ⅱ) with an octahedral environment. Room temperature magnetic studies show that there are weak antiferromagetic interactions between the two metal ions within a molecule.
