Five new coordination assemblies of substituted zinc(II) isophthalates and H2pbbp H2pbbp = N,N′-[(1,4-phenylene)bis(methylene)]bis(pyridine-4-carboxamide)} linkers, namely, [Zn(pbbp)(Fip)]n, 1, [Zn(pbbp)(Nip)∙H2O]n, 2, [Zn(pbbp)(Mip)∙H2O]n, 3, [Zn(pbbp)(Bip)·H2O]n, 4, [Zn(pbbp)(TM)(H2O)·H2O]n, 5 have been synthesized under hydrothermal conditions. Single-crystal X-ray diffraction analysis reveals
取代的锌的五个新的协调组件(II)间苯二甲酸酯和H 2 PBBP H 2 PBBP = Ñ,Ñ ' - [(1,4-亚苯基)二(亚甲基)]二(吡啶-4-甲酰胺)}接头, 即 [Zn(pbbp)(Fip)] n , 1 , [Zn(pbbp)(Nip)∙H 2 O] n , 2 , [Zn(pbbp)(Mip)∙H 2 O] n , 3 , [Zn(pbbp)(Bip)·H 2 O] n , 4 , [Zn(pbbp)(TM)(H 2 O)·H 2 O] n , 5是在水热条件下合成的。单晶 X 射线衍射分析显示化合物1-5表现出二维层状结构。由于强氢键,化合物1-4中的层状结构进一步扩展为三维超分子网络。还研究了这些化合物的热稳定性、粉末 X 射线衍射、红外光谱和发光特性。
