A novel coordination polymer [Zn_2(BTA)_2(TDC)]_n(HBTA = benzotriazole, H_2TDC = thiophene-2,5-dicarboxylic acid) has been synthesized by the reaction of zinc(Ⅱ), H_2TDC and HBTA. This compound is fully structurally characterized by elemental analysis, IR, and single-crystal X-ray crystallography. The bulk new materials were further identified by X-ray powder diffraction. Compound 1 crystallizes in the orthorhombic system, space group Pbcn, with a = 9.8825(8), b = 9.4047(8), c = 20.5567(17) ?, V = 1910.6(3) ?~3, C_(18)H_(10)N_6O_4SZn_2, M_r = 537.12, D_c = 1.867 g/cm~3, μ(MoK α) = 2.662 mm~(-1), F(000) = 1072, Z = 4, S = 1.058, the final R = 0.0201 and w R = 0.0530 for 1700 observed reflections(I > 2σ(I)). Its compositional stability and photoluminescence properties were further investigated to establish the structure-property relationships. Structural analysis reveals that this compound is a 3D(4, 4)-connected framework with the(6~6)(6~4·8~2) topology.
