| 摘 要： | 由水热法合成了2个铜配合物Cu(INAIP)(bbi)]·5H2O (1)和Cu(INAIP)(phen)(H2O)]·H2O (2)(H2INAIP=5-异烟酰胺基异酞酸，bbi=1，4-二咪唑基丁烷，phen=1，10-邻菲咯啉)，并用元素分析、IR及X-射线单晶衍射等对其进行了表征。晶体结构分析结果表明：配合物1和2都属于单斜晶系，C2/c空间群。配合物1是由1，4-二咪唑基丁烷连接Cu(INAIP)]一维链形成的二维双层结构，而配合物2是通过π-π堆积作用将Cu(INAIP)]一维无限链延伸为二维结构，这2个化合物最终均被氢键拓展成三维超分子结构。在1.8~300 K温度范围内测试了配合物1和2的变温磁化率，结果表明配合物1中由羧基桥联的双核铜之间存在弱的反铁磁相互作用，而配合物2表现为顺磁性。

| Abstract: | Two Cu(Ⅱ) complexes Cu(INAIP)(bbi)]-5H2O (1) and Cu(INAIP)(phen)(H2O)]-H2O (2) were obtained by hydrothermal reactions of CuCl2·2H2O with 5-(isonicotinamido)isophthalic acid (H2INAIP) and N-donor ligands of l,1'-(1,4-butanediyl)-bis(imidazole) (bbi) and 1,10-phenanthroline (phen), respectively. Both compounds crystallize in monoclinic space group C2/c. Single crystal X-ray diffraction analysis revealed that the bbi ligands connect Cu(INAIP)] ID chains to form 2D bi-layers in complex 1, while complex 2 displays a 1D chain structure, extending to 2D net through the Π-Π interactions. Complexes 1 and 2 are finally extended to 3D supramolecular structures by hydrogen bonding interactions. In addition, the magnetic property of complexes 1 and 2 has been investigated in the temperature range of 1.8～300 K, and the results show the weak antiferromagnetic interactions between the two Cu(Ⅱ) ions bridged by carboxylate groups in 1, and the paramagnetic behavior of 2.
