摘要
用金属离子作模板通过N－氧化吡啶－2，6－二甲醛与1，3－丙二胺缩合得到了新型大环水溶性希夫碱金属配合物Ni2LCl6·C2H5OH·10H2O，对其进行了元素分析、红外光谱、电化学及热稳定性能的研究．结果显示：Ni2L配合物的电极反应可以认为是一个双电子传输过程，并且电极过程是一个不可逆过程，求得它的扩散系数为4．07×10－6cm2·s-1．该配合物的稳定性较好，约在563℃配合物发生分解，失去有机基因，生成氧化物．
A new macrocyclic dinuclear nickel(Ⅲ) complex, prepared by the condensation of 2,6diformylpyridine N-oxide with 1,3-diaminopropane in the presence of Ni(Ⅱ)Cl2.6H2O and formulated as Ni2LC16 .C2 H5 OH 10H2O, was characterized by elemental analyses, infrared spectrum, differential thermal analysis (DTA), thermogravimetry(TG) and investigated electrochemically. Theresults show that two nickel ions are situated at the same chemical environments in the compoundand the electrode reaction can he thought as a double electron transfer process which is irreversible.The diffusion coefficient is 4.07 x 10-6cm2 s-1. The Ni complex exhibited good thermal stability,it decomposed with loss of its organic portion and the formation of Ni2O3 as a final product at563 ℃
