Crystal Structure, Electrochemical and Fluorescent Properties of a New Cadmium(Ⅱ)Complex Cd(C12H6O4N2)(Phen)2(H2O)·3H2O

摘要

A new Cd(Ⅱ)complex[Cd(C12H6O4N2)(Phen)2(H2O)]·3H2O with 2,2-bipyridine-3,3-dicarboxylic acid as a ligand has been synthesized.Crystal data for the title complex are as follows:monoclinic,space group P21/n,a=12.8458(5),b=17.9131(7),c=15.2960(6),β=111.7430(10)o,V=3269.3(2)3,Dc=1.581 g/cm3,Z=4,μ(MoKα)=0.731 mm-1,F(000)=1580,the R=0.0244 and wR=0.0605.In the title complex,the central Cd(Ⅱ)ion is located in a distorted octahedral coordination environment.The electrochemical and fluorescent properties of the title complex were studied.The results show that the electron transfer of the title complex is irreversible in the electrode reaction and it has a broad emission peak in the range of 470~508 nm with the excitation wavelength of 488 nm.
