Synthesis,Crystal Structure,Luminescent and Electrochemical Properties of a New Binuclear Cd(Ⅱ) Complex with 2,4-DAA as Ligand

The study of carboxyl complexes has drawn great interests,mainly because of their intriguing variety of architectures and topologies as well as potential applications in many fields,such as functional materials,biochemistry,medicine,and so

One new complex Cd2（2,4-DAA）4（2,2＇-bipy）2 with 2,4-dichlorophenoxy acetic acid（2,4-DAA） and 2,2＇bipyridine（2,2＇-bipy） as ligands has been synthesized and characterized.Crystal data for this complex are as follows：monoclinic,space group P1,a=1.049 9（2） nm,b=1.094 2（2） nm,c=1.185 7（2） nm,α=96.70（3）°,β=105.20（3）°,γ= 91.75（3）°,V=1.303 0（5） nm3,Dc=1.806 g·cm-3,Z=2,μ（Mo Kα）=1.295 mm-1,F（000）=704,final discrepancy factors R1=0.042 1,wR2=0.102 1.In the crystal,two neighboring Cd（Ⅱ） ions are bridged by four 2,4-dichlorophenoxy acetic radicals,and their end positions are coordinated with two 2,2＇-bipyridine molecules,forming a binuclear cage structure.The coordination environment of each cadmium（Ⅱ） ion is CdO4N2,giving a distorted triprism coordination geometry.Luminescent property and the cyclic voltammetric behavior of the complex were investigated.CCDC：781765.
