Three novel coordination polymers (CPs), formulated as [Co₂(TZI)(OH)(H₂O)₂]_n (1), {[Co(H₂TZI)₂(BIB)(H₂O)₂]·(H₂O)₂}_n (2), and [Ni(HTZI)(BPB)(H₂O)]_n (3) (H₃TZI = 5-(1H-tetrazol-5-yl)isophthalic acid, BIB = 1,4-bi(1-imidazolyl)benzene, and BPB = 1,4-bi(1- pyridyl)benzene), have been synthesized under hydrothermal methods, using 5-(1H-tetrazol-5-yl)isophthalic acid ligand (H₃TZI) and two different N-donating ancillary ligands. Their structures have been determined by single-crystal X-ray diffraction analysis, elemental analysis (EA), IR spectra (IR), powder X-ray diffraction (PXRD), and thermogravimetric analysis (TGA). X-ray single-crystal diffraction analyses reveal that complex 1 possesses a 2D bilayer structure, complex 2 displays a 3D supermolecular structure with a Co(H₂TZI)₂ SBU by H-bond interactions between neighbouring 1D chains, and complex 3 presents a 2D framework with a dinuclear [Ni₂N₄]²⁺ SBU. Furthermore, the magnetic properties of 1–3 have been investigated, the results show there are antiferromagnetic interactions between the Co ions in 1 and 2, and the ferromagnetic interactions between Ni ions in 3.

三种新型配位聚合物（CPs），配制成[Co ₂（TZI）（OH）（H ₂ O）₂ ] _n（1），{[Co（H ₂ TZI）₂（BIB）（H ₂ O）₂ ] ·（H ₂ O）₂ } _n（2）和[Ni（HTZI）（BPB）（H ₂ O）] _n（3）（H ₃ TZI = 5-（1H-四唑-5-基）间苯二甲酸，BIB = 1,4-双（1-咪唑基）苯和BPB = 1,4-双（1-吡啶基）苯）是在水热法下使用5-（1H-四唑-5-基）合成的间苯二甲酸配体（H ₃TZI）和两个不同的N-供体辅助配体。它们的结构已通过单晶X射线衍射分析，元素分析（EA），红外光谱（IR），粉末X射线衍射（PXRD）和热重分析（TGA）确定。透视单晶衍射分析表明，复杂1具有一个2D双层结构，复杂的2只显示一个三维超分子结构与钴（H ₂ TZI）₂由相邻一支维链，和复合物之间的氢键相互作用SBU 3所呈现具有双核[Ni ₂ N ₄ ] ²⁺ SBU的2D框架。此外，1 –对3进行了研究，结果表明1和2中的Co离子之间存在反铁磁相互作用，而3中的Ni离子之间存在反铁磁相互作用。
