摘要
合成了一种二 ( 3 羧基水杨醛叉 )缩 1 ,3 丙二胺 (TS)Schiff碱为配体的Cu(Ⅱ ) VO(Ⅱ )异双核配合物CuVO(TS)·MeOH。用元素分析、摩尔电导、IR光谱、UV光谱对配合物的组成和结构进行了表征。采用循环伏安法研究了配合物的电化学性质。研究表明 ,由于第 2金属离子的配位增强了内部铜离子的稳定性 ;在 4~3 0 0K范围内测量了配合物的变温磁化率 ,经拟合得磁参数J =-1 63 1 2cm-1,表明在此异双核配合物中 ,金属离子间存在较弱的反铁磁自旋交换作用。
Heterobinuclear complex CuVOTS·MeOH, where TS is the schiff base N,N′-bis(3-carboxylsalicylidene)trimethylenediamine, was synthesized and characterized by elemental analysis, IR and UV-vis spectra. The electrochemical property of the complex was examined by cyclic voltammetry in DMSO. The results show that the coordination of the second metal ion could increase the stability of the inner copper(Ⅱ) ion. The temperature dependence of the magnetic susceptibility of Cu(Ⅱ)-VO(Ⅱ) over the range 4~300 K gave the exchange integral J=-1.631 2 cm -1, which indicates the presence of weak antiferromagnetic interaction between the internal Cu 2+ ion and the outer VO 2+ ion in the heterobinuclear complex.
