Five new coordination polymers (CPs), namely, [Co(DIPT)₂]_n (HDIPT = 5-(3,5-di(1H-imidazol-1-yl)phenyl)-2H-tetrazole, 1), [Zn(DIPT)₂]_n (2), {[Cu(DITP)₂(H₂O)₂]·3H₂O}_n (3), and{[Cu(DITP)]·DMF}_n (4 and 5) based on a rigid tripodal nitrogen-containing heterotopic ligand were obtained under hydrothermal conditions. Compounds 1–2 are isostructural and exhibit 3D frameworks with relative rare two-folded interpenetrating (3,6)-connected pyr network topologies. Compound 3 is a 2D layer with (4,4) network topology if consider Cu(II) as topological node and DIPT^- ligand as linker. Compounds 4–5 are topological supramolecular isomers obtained from pre-synthesized and in situ formed HDIPT, respectively. The coordination modes of Cu(I) ion and DIPT^- ligand, as well as the 1D zigzag chain building block in compounds 4 and 5 are quite similar, but they are with different 4-connected gis and sra topologies, respectively. In the frameworks, the tetrazolyl group has more contributions to the formation of well-defined building blocks, while the imidazolyl group has more contributions to the linkage of the building blocks. The combination of both tetrazolyl group and imidazolyl are suitable for constructing new interesting CPs. Furthermore, the thermal stabilities and solid-state fluorescent properties of selected compounds have been investigated.

五个新的配位聚合物（CP），即[Co（DIPT）₂ ] _n（HDIPT = 5-（3,5-二（1H-咪唑-1-基）苯基）-2H-四唑，1），[Zn （DIPT）₂ ] _n（2），{[Cu（DITP）₂（H ₂ O）₂ ]·3H ₂ O} _n（3）和{[Cu（DITP）]·DMF} _n（4和5 ）基于刚性三角架含氮配体异位进行水热条件下获得的。化合物1-2具有同构结构，并展示具有相对罕见的两重互穿（3,6）连接的吡咯网络拓扑的3D框架。化合物3是2D层（4,4）的网络拓扑结构，如果考虑的Cu（II）的拓扑节点和DIPT ^-配体作为连接器。化合物4-5是分别从预合成和原位形成的HDIPT获得的拓扑超分子异构体。的Cu（I）离子和DIPT的配位模式^-配体，以及化合物中的Z字形1D链构建块4和5很相似，但它们是不同的4-连接的GIS和SRA拓扑。在这些框架中，四唑基对确定的结构单元的形成有更大的贡献，而咪唑基对结构单元的连接有更多的贡献。四唑基和咪唑基的组合适合构建新的有趣的CP。此外，已经研究了所选化合物的热稳定性和固态荧光性质。
