摘要： 以N-(2-羧基苯)-N’-(氨乙基)草酰胺根阴离子(oxbe)为桥联配体, 端接二丙烯三胺(dpt), 合成了铜镍异双核配合物[Cu(oxbe) Ni(dpt)(H2O)]ClO4·0.5H2O. 通过元素分析和IR 光谱对配合物进行了表征, 利用X射线单晶衍射测定了其晶体结构. 该化合物分子间通过氢键相互作用, 形成双链状超分子结构. 5—300 K 变温磁化率研究结果表明, 化合物中双核体系 Cu(SCu=1/2)-Ni(SNi=1) 中心原子间通过草酰胺桥联发生较强的反铁磁相互作用(磁参数J=-62.3 cm-1, g=2.11).

Abstract: A new heterobinuclear complex bridged by N-benzoato-N'-(2-aminoethyl)oxamido trianion(oxbe) and end-capped with dipropylenetriamine(dpt), [Cu(oxbe)Ni(dpt)(H2O)]ClO4·0.5H2O, was synthesized and characterized by elemental analyses and IR spectra. The crystal structure was determined by single-crystal X-ray diffraction analyses. There are hydrogen bonds in the complex resulting in the formation of the double chainlike supramolecular architecture. The variable temperature magnetic susceptibility measured at 5—300 K indicates the presence of a medial antiferromagnetic interaction through the oxamido bridge in binuclear system Cu(SCu=1/2)-Ni(SNi=1) with magnetic parameters J=-62.3 cm-1, g=2.11.
