由水热法合成了2个铜配合物[Cu(INAIP)(bbi)]·5H2O(1)和[Cu(INAIP)(phen)(H2O)l·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l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个化合物最终均被氧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.

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.
