摘要 Hydrothermal reactions of 5-（tetrazol-5-yl） isophthalic acid with cadmium nitrate/praseodymium nitrate led to two complexes of [Cd3（TZI）2（H2O）（11）]n（1） and [Pr（TZI）（H2O）5]n（2）. Their structures and properties were determined by X-ray diffraction, IR spectroscopy, fluorescence spectrum, thermal gravimetric analyses and elemental analysis. Complex 1 belongs to monoclinic system, I2/c space group, with a = 12.8688（3）, b = 18.0925（3）, c = 14.5190（3）A, β = 116.054（3）°, V =3036.92（13） A^3, Z = 4; complex 2 crystallizes in triclinic, space group P 1, with a = 7.9690（5）, b =9.7665（8）, c = 10.4353（9） A, α = 116.709（9）, β = 107.461（6）, γ = 95.671（6）°, V = 665.54（9）A^3 and Z =2. Complex 1 is a 3D planar structure. Complex 2 is a one-dimensional double chain configuration and extends into a 3D network by hydrogen bonds and π-π interactions.
