Synthesis,Crystal Structure and Properties of a Zinc(Ⅱ) Complex Based on 5-(1H-Tetrazol-5-yl)isophthalic Acid Ligand

A novel polymeric zinc(II) complex {Zn_2(TIA)(H_2O)_3]?(NO_3)}_n(1, H_3TIA = 5-(1H-tetrazol-5-yl)isophthalic acid) has been synthesized in mixed solvents under solvothermal conditions and characterized by elemental analysis, IR spectroscopy and X-ray single-crystal diffraction. Complex 1 crystallizes in orthorhombic, space group Cmcm with a = 10.4210(6), b =23.3526(14), c = 6.9214(4) ?, V = 1684.37(17) ?3, Z = 4, C_9H_4N_5O_(10)Zn_2, Mr = 472.91, Dc = 1.865g/cm~3, F(000) = 932, λ(MoK α) = 2.909 mm-1, R = 0.0423 and wR = 0.1287. The complex has good thermal stability and excellent photoluminescent property.
