Two three-dimensional (3D) coordination polymers, viz. [Ni(INAIP)(Him)(H2O)]·H2O (1) and [Fe(INAIP)(H2O)2]·H2O (2), were synthesized by reaction of 5-(isonicotinamido)isophthalic acid (H2INAIP), NiSO4·6H2O/FeSO4·7H2O, and N-donor ligands, namely 1H-imidazole or 4,4′-bipyridine, under hydrothermal conditions. Single-crystal X-ray diffraction analysis indicated that [Ni(INAIP)(Him)(H2O)]·H2O has a two-dimensional (2D) layer network structure with (6, 3) topology, while 2 shows a 3D fourfold interpenetrating framework with (103-b) topology. The thermal stability and magnetic and adsorption behavior in solid state of the complexes were investigated in detail. Moreover, the photocatalytic degradation of methylene blue (MB) over complex 1 was studied.

5-(异烟酰胺)间苯二甲酸构成的两种配位聚合物的合成、结构和性质

两种三维 (3D) 配位聚合物，即。[Ni(INAIP)(Him)(H2O)]·H2O (1) 和 [Fe(INAIP)(H2O)2]·H2O (2)，由 5-(异烟酰胺)间苯二甲酸 (H2INAIP) 反应合成， NiSO4·6H2O/FeSO4·7H2O和N-供体配体，即1H-咪唑或4,4'-联吡啶，在水热条件下。单晶X射线衍射分析表明[Ni(INAIP)(Him)(H2O)]·H2O具有具有(6, 3)拓扑结构的二维(2D)层网络结构，而2显示出3D四重互穿具有（103-b）拓扑的框架。详细研究了配合物在固态下的热稳定性和磁性和吸附行为。此外，还研究了配合物 1 上亚甲蓝 (MB) 的光催化降解。
