A New Zn(Ⅱ) Coordination Polymer Constructed from 1,3,5-Benzenetricarboxylate Ligand Exhibiting Photoluminescence

摘要

The title Zn(Ⅱ) coordination polymer {[Zn2(BTC)(HBTC)(dpa)(Hdpa)]·3H2O}n(1,H3BTC =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 P-1,a =9.9415(4),b =13.5859(8),c =15.2987(5) （A）,a =96.301(4),β =107.944(3),γ =103.575(4)°,V =1873.48(14) (A)3,Z =2,μ =1.365 mm-1,Dc =1.672 g/cm3,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.
