Hydrothermal Synthesis,Crystal Structure and Property of a Threedimensional Compound[Zn(INAIP)(Bipy)]·3H2O

由水热法合成了锌化合物[Zn(INAIP)(Bipy)]·3H2O(1),(H2INAIP=5-异烟酰胺基异酞酸,Bipy=4,4’-bipyridine),并对其进行了元素分析、IR及X-射线衍射法表征。晶体结构表明:配合物1属于单斜晶系,P 21/c空间群。配合物1是由桥联配体5-异烟酰胺基异酞酸连接成二维层状结构,该二维层被Bipy配体连接成三维网络结构。此外,配合物1具有较强的荧光性能,且化合物1对CO2有一定的选择性吸附作用。

A new zinc metal-organic coordination polymer[Zn(INAIP)(Bipy)]·3H2O(1)was obtained by hydrothermal assembly of Zn(OAc)·2H2O with 5-(isonicotinamido)isophthalic acid(H2INAIP)in the presence of N-donor ligands,namely 4,4’-bipyridine(Bipy).And the resulting complex were characterized by IR spectrum,EA and single-crystal X-ray diffraction.Coordination compound 1 belongs to monoclinic system,space group P 21/c.Single-crystal X-ray diffraction analysis revealed that each INAIP2-ligand in turn uses its two carboxylate groups to connect three metal centers,then the two-dimensional(2D)layer is formed,lastly,the layer was pillared by Bipy to form 3D network.On the other hand,complex 1 exhibits a strong photoluminescence in the solid state at room temperature,which 1 displays selective adsorption behavior of CO2 over N2 at 273K.
