摘 要: | The title Zn(II) coordination polymer {[Zn_2(BTC)(HBTC)(dpa)(Hdpa)]·3H_2O}_n(1,H_3BTC = 1,3,5-benzenetricarboxylic acid,dpa = 4,4?-dipyridylamine),has been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction,powder X-ray diffraction,IR spectroscopy and Fluorescence spectroscopy.Complex 1 belongs to the triclinic system,space group P1,a = 9.9415(4),b = 13.5859(8),c = 15.2987(5) ?,α = 96.301(4),β = 107.944(3),γ = 103.575(4)°,V = 1873.48(14) ?~3,Z = 2,μ = 1.365 mm~(-1),Dc = 1.672 g/cm~3,Mr = 943.44,F(000) = 964,the final R = 0.0314 and wR = 0.0710 with I 2σ(I).Complex 1 displays a two-dimensional bilayer coordination polymer.Complex 1 shows fluorescence in the solid state at room temperature.
