由水热法合成了一个混核金属配位聚合物{[CoEu2(INAIP)4(H2O)6]·2.5H2O}n (1)(INAIP2-=异烟酰胺基间苯二甲酸根),并对其进行了元素分析、IR及X-射线衍射法表征.晶体结构研究表明:配合物1属于三斜晶系,P(1)空间群.配合物1是由配体异烟酰胺基间苯二甲酸连接而成的二维双层状结构,该二维层通过氢键拓展为三维超分子结构.配合物1的荧光测试研究表明它具有典型的稀土铕离子红色荧光.

A 3d-4f coordination polymer {[CoEu2(INAIP)4(H2O)6]· 2.5H2O}n (1) was obtained by hydrothermal assembly of Co(OAc)2·4H2O and Eu(NO3)3·6H2O with H2INAIP (5-(isonicotinamido)isophthalic acid).Complex 1 crystallizes in triclinic,space group P(1) with a=1.008 89(13) nm,b=1.082 34(14) nm,c=2.979 5(4) nm,V=3.200(7) nm3,Z=1,C112H90Co2Eu4N16O57,Mr=3 297.70,Dc=1.711 g·cm-3,μ=2.285 mm-1,F(000)=1636,Rint=0.025 8,R=0.049 2,wR=0.126 3.Single-crystal X-ray diffraction analysis revealed that each INAIP2- ligand uses its two carboxyl groups to connect two/three lanthanide centers,and the Co(Ⅱ) only bonds to the pyridyl group and terminal water molecules,then forming the two-dimensional (2D) bilayer.On the other hand,the 2D layers are further connected by hydrogen bonds interactions to give a three-dimensional (3D) supramolecular structure.In addition,the luminescent property of complex 1 has been investigated at room temperature,indicating the red photoluminescence exists in it.CCDC:834796.
