Abstract: Three new Zn-II-ditetrazolate coordination polymers (CPs), namely [Zn(m-pdtz)(4,4'-bipy)(H2O)](n) (1), [Zn2Cl2(m-pdtz)(4,4'-bipy)](n) (2) and [Zn-2(OH)(2)(m-pdtz)](n) (3) (4,4'-bipy = 4,4'-bipyridine, m-H(2)pdtz = 5,5'-1,3-phenylene-ditetrazole), have been constructed by an in situ ditetrazolate-ligand synthesis system. The formation of m-pdtz(2-) ligand involves the Sharpless [2 + 3] cycloaddition reaction between isophthalonitrile (IPN) and NaN3 in the presence of Zn2+ ions as Lewis-acid catalysts under hydro/solvothermal conditions. Single-crystal structural analyses reveal that compound 1 exhibits a new 6-connected 3D structural topology constructed from dimeric {Zn-2} clusters as secondary building units (SBUs), compound 2 represents a 2D sql structural feature built from rhombic tetrameric {Zn-4} rings as SBUs, while compound 3 displays a new (4,6)-connected 3D structural topology constructed from rod-shaped 1D Zn-chains as SBUs. Regarding these three CPs, we have performed a thorough investigation on their crystal structure, topology, and fluorescence property.
