合成了一种新的不对称草酰胺桥联异双核配合物 [Cu(oxbe) Mn(phen) 2 ]Cl O4· 3H2 O[oxbe表示 N- (2 -羧基苯 ) - N′- (2 -氨乙基 )草酰胺的 - 3价阴离子 ,phen代表 1,10 -邻菲林 )。用元素分析、红外光谱、电子光谱、EPR谱等对所合成的配合物进行了结构表征 ,推测该化合物具有草酰胺桥联结构 ,铜离子为平面正方构型 ,锰离子为八面体构型。在 5～ 30 0 K范围测量了标题化合物的变温磁化率 ,经最佳拟合分别得磁参数 J=- 2 9.3cm-1,表明在异双核配合物中金属离子间有较弱的反铁磁性自旋交换作用
A new asymmetric oxalic acid bridged heteronuclear complex [Cu (oxbe) Mn (phen) 2] Cl O4 · 3H2O [oxbe represents N- (2 - carboxyphenyl) Aminoethyl) oxalamide, phen stands for 1,10-phenanthrene). The complex was characterized by elemental analysis, IR, EPR and EPR. It was speculated that the compound had oxalic acid bridged structure, copper ion was planar square and manganium was octahedron. The temperature-dependent magnetic susceptibility of the title compound was measured in the range of 5 ~ 30 0 K, and the best fitting result was the magnetic parameter J = -2 9.3cm-1, indicating that the heterodinuclear complex has a weak antiferroic Magnetic spin exchange
