【摘要】 合成了四种新型具有草酰胺桥联大环二羰四胺结构Cu(Ⅱ ) -M(Ⅱ ) (M =Mn ,Ni,Cu ,Zn)的双核配合物 ,并用元素分析 ,红外光谱 ,紫外光谱 ,摩尔电导 ,热重分析 ,室温磁矩等手段对其进行了结构表征 .经研究推定 ,此配合物具有草酰胺桥联结构 ,Cu(Ⅱ )处于平面正方场M(Ⅱ )处于八面体场中 .室温磁矩测定表明通过草酰胺桥联配体金属离子间有一定的反铁磁性自旋偶合相互作用
【Abstract】 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.
【Key words】 oxalamide bridge; heterobinuclear complexes; antiferromagetic;
