Two one-dimensional coordination polymers [Mg(Himdc)(DMF)(H2O)]n (1) and [Mg(Hpdc)(H2O)2]n (2) have been hydrothermally synthesized by the reactions of Mg(NO3)2·6H2O and 4,5-imidazoledicarboxylic acid or 3,5-pyrazoledicarboxylic acid, and characterized by elemental analysis, FTIR, thermal gravimetric analysis and X-ray diffraction single-crystal structural analysis. Two compounds crystallize in the orthorhombic and monoclinic, space group P212121 and P21/c for 1 and 2, respectively. Compound 1 shows one-dimensional zigzag chain structure, compound 2 shows one-dimensional linear chain structure, the chain and chain of 1 and 2 are both connected by hydrogen bonds to form three-dimensional structure. The fluorescence spectra of 1 and 2 were measured, the luminescence behaviors probably results from π→π* electronic transition of the respective ligand. CCDC: 832380, 1;832381, 2.%本文以Mg(NO3)2· 6H2O分别与4,5-咪唑二羧酸(4,5-imidazoledicarboxylic acid,H3imdc)和3,5-吡唑二羧酸(3,5-pyrazoledicarboxylic acid,H3pdc)通过水热反应合成了2个新型镁的一维配位聚合物[Mg(Himdc)(DMF)(H2O)]n(1)和[Mg(Hpdc)(H2O)2]n (2),并对配位聚合物1和2进行了元素分析、FTIR、热重分析和X-射线单晶结构解析等表征.X-射线单晶结构解析表明配位聚合物1和2的晶体分别属于正交晶系与单斜晶系,空间群分别为P212121和P21/c.配合物1为一维Z字型链状结构,配合物2为一维线型链状结构,2个配合物中的链与链之间均通过氢键相互作用堆积成三维结构.对1和2进行固态荧光光谱分析,结果显示,1和2的荧光发射峰与各自的配体的荧光发射峰峰形一致,说明2个配合物的荧光发射峰应归属于各自配体内的π→π*电子跃迁.
