摘要
合成了两种新的双核铜配合物［Cu2L3］ClO4·nH2O，其中L为4－（邻羟苯基亚甲基）亚胺－3，5－二甲基－1，2，4－三唑（A）和4－（邻羟苯基亚甲基）亚胺－，5－二乙基－1，2，4－三唑（B），通过元素分析、红外光谱、电子光谱等手段表征，推断配合物具有酚氧桥的结构，CU（Ⅱ）离子配位环境为畸变四方构型．配合物（A）的变温磁化率表明铜离子间有反铁磁相互作用，g＝2．07，2J＝-136．9cm-1。
Two new metal complexes of [Cu2L3]ClO4. nH2O were synthesized, where L=4-sal-icylidene imino-3, 5-dimethyl-1. 2. 4-triazole (A) L = 4-salicylidene imino3, 5-diethyl-1.2.4-triazole (B). Based on IR, elemental analyses and electronic spectra, the complexes have phenoxy-bridged structure and both copper(Ⅱ) ions are in a distorted planar coordination environment. Variable-temperature magnetic susceptibility (4-300K) data for complex (A) show that there is aniferromagnetic spin exchang interaction between two Cu (Ⅱ)ions, with a 2J=-136. 9cm-1and g=2.07.
