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.
