双核镉配合物的合成及结构

Synthesis and Crystal Structure of Dinuclear Cd(Ⅱ) Complex

本文以烟酸为原料合成得到了有机配体1-(3-吡啶基)丁烷-1,3-二酮,再同Cd(NO3)2.4H2O进行配位反应,得到一双核镉配合物。采用1H NMR、UV-vis、FTIR等技术对其组成进行了表征,并经X衍射测定了配合物的单晶结构。结构分析表明,配合物晶体属于单斜晶系。a=15.666(5),b=7.701(2),c=22.526(7);α=90°,β=107.83(3),γ=90,°V=2.5871(13)nm3,Z=4,Dc=1.893g.cm-3,μ=1.718mm-1,F(000)=2120,the f inal R=0.0286,wR=0.0743。

Organic ligand 1-（3-pyridyl）-1,3-butanedione were synthesized from nicotinic acid,futhermore the dinuclear Cd（II） complex was obtained via the reaction of ligand with Cd（NO3）2·4H2O.The ligand and the complex were charactered by 1H NMR,UV-vis,FTIR,and the structure of the dinuclear Cd（II） complex was measured by single crystal X-ray diffraction analysis.The results of structural analysis indicate that the structure of the dinuclear Cd（II） complex belongs to monoclinic system,and a=15.666（5）,b=7.701（2）,c=22.526（7）,α=90°,β=107.83（3）,γ=90°,V=2.587.1（13）nm3,Z=4,Dc=1.893 g·cm-3,μ=1.718 mm-1,F（000）=2120,the f inal R=0.0286,wR=0.0743.
