摘要
通过回流加热法以吡啶-2,3-二羧酸(2,3-PDC)和2-甲基咪唑(DMIM)配体与金属Zn(Ⅱ)离子反应合成了配合物[Zn(2,3-PDC)(H2O)(DMIM)·H2O]n(1),用IR、热重分析和X-射线单晶衍射对配合物结构进行表征。X-射线研究结果显示配合物1中锌离子通过2,3-PDC配体桥联形成一维链结构。荧光光谱测量显示配合物的最大发射波长为473nm。
The complex[Zn(2,3-PDC)(H2O)(DMIM)·H2O]n(1)were synthesized based on obtained from 2,3-pyridinedicarboxylic acid(2,3-PDC),2-methylimidazole(DMIM)and metal Zn^2+cations under the condition of reflux heating.The structure was characterized by IR,thermogravimetric analysis and single-crystal X-ray diffraction and fluorescence spectra.The X-ray crystallographic studies suggest that the Zn(Ⅱ)ions in complex 1 are bridged by the 2,3-PDC ligands to form a one-dimensional chain.The fluorescence spectra of complex 1 show that there is a strong emission peak at 473 nm.
