通过吡啶酰胺类配体3,5-二(4-吡啶酰胺基)吡啶(4-DPBA)与相应金属盐反应,合成了3个配位聚合物{[Zn(4-DPBA)2(NO3)2]·4DMF}n(1),{[Cd(4-DPBA)2(NO3)2]·4DMF}n(2)和{[Cu(4-DPBA)2(DMF)2](ClO4)2·7DMF· 2H2O}n(3),并用红外光谱、元素分析、粉末及单晶X-射线衍射等方法对其进行了表征.结果表明配合物1和2是同构的,由平行的一维带状链通过氢键连接而成二维层状结构,而配合物3是由3种不同取向的一维带状链构成二维多层结构.这3个配合物最终均通过氢键连接形成三维超分子结构.研究了配合物1和2的荧光性质.

Three new coordination polymers {[Zn(4-DPBA)2(NO3)2] ·4DMF}n (1),{[Cd(4-DPBA)2(NO3)2]·4DMF}n (2)and {[Cu(4-DPBA)2(DMF)2](ClO4)2·7DMF·2H2O}n (3) were synthesized by reactions of pyridyl and amidecontaining ligand N,N'-di(pyridin-4-yl)-pyridine-3,5-dicarboxamide (4-DPBA) with corresponding metal salt.All the complexes were characterized by FTIR,elemental,powder and single crystal X-ray diffraction analyses.The results show that complexes 1 and 2 are isostructural and have two-dimensional (2D) layer structure with parallel one-dimensional (1D) ribbon-like chains hnked by hydrogen bonds,while complex 3 possesses 2D networks with three different orientations of 1D chains connected by hydrogen bonds.All the complexes show three-dimensional (3D) supramolecular structures through hydrogen bonding interactions.The photoluminescent property of complexes 1 and 2 was investigated.CCDC:879335,1; 879366,3.
