N-(2-羧基苯)-N'-(3-氨丙基)草酰胺桥联异双核配合物的合成、电化学性质和磁性
摘要:
合成了4种不对称草酰胺桥联异双核配合物[Cu(oxca)M(phen)2]ClO4·2H2O[oxca表示N-(2-羧基苯)-N'-(3-氨丙基)草酰胺三价阴离子,phen代表邻菲啉,M=Mn、Co、Ni、Zn].用元素分析、红外光谱、电子光谱、热分析及室温磁矩等对所合成配合物进行了表征.在DMSO溶剂中采用循环伏安法研究了配合物的电化学性质.在4~300K范围测量了Cu(Ⅱ)-Mn(Ⅱ)和Cu(Ⅱ)-Ni(Ⅱ)的变温磁化率,经拟合分别得磁参数J=-10.56cm-1和J=-17.08cm-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.

Sythesis,Electrochemical and Magnetic Properties of Heterobinuclear Complexes Bridged by N-(2-Carboxy phenyl)-N'-(3-aminopropyl) oxamide
Abstract:
Four novel heterobinuclear complexes have been synthesized,[Cu(oxca)M(phen)2]ClO4·2H2O where oxca=N-(2-carboxy phenyl)-N'-(3-aminopropyl) oxamide; phen=1,10-phenanthroline; M=Mn2+, Co2+, Ni2+, Zn2+. The results obtained from IR、elemental analysis、thermogravimetric analysis conductivity, electronic spectrum and room temperature magnetic moment measurements showed these complexes appeared to have extended oxamido-bridged structures. The electrochemical properties of the heterobinuclear complexes have been measured by cyclic votammetry in DMSO. The temperature dependence of the magnetic susceptibility of Cu(Ⅱ)-Mn(Ⅱ) and Cu(Ⅱ)-Ni(Ⅱ) over the range 4~300 K gave the exchange integral of J=-10.56 cm-1 and J=-17.08 cm-1.
