A New Cd(Ⅱ) Coordination Compound Based on 4-(1,2,4-Triazol-4-yl)phenylacetic Acid:Synthesis, Structure and Photoluminescence Property

摘要

A new complex [Cd2(L)2(C1)2(H2O)]n (1) was synthesized by reacting CdC12·2.5H2O with 4-(1,2,4-triazol-4-yl)phenylacetic acid (HL) ligand.The structure of the complex was characterized by single-crystal X-ray diffraction,IR spectroscopy,elemental analysis and PXRD.Complex 1 crystallizes in triclinic,space group P21/c with a =11.4303(8),b =14.1792(10),c =14.6857(10) (A),β =96.3780(10)°,V =2365.4(3) (A)3,Z =4,C2oH16Cl2N6OsCd2,Mr =716.09,Dc =2.011 g/cm3,μ =2.069mm-1,S =1.051,F(000) =1392,the final R =0.0458 and wR =0.0949 for 5402 observed reflections (Ⅰ ＞ 2σ(Ⅰ)).Complex 1 is a two-dimensional (2D) layer structure and non-covalent bonding interactions such as C-H…π and π…π extend the 2D to form a three-dimensional supramolecular polymer.
