水热合成了一个的杂金属配合物{[NiTb2(INAIP)4(H2O)6]·8H2O}n(1)([NAIP2-=异烟酰胺吡啶基异酞酸根),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是由配体异烟酰胺吡啶基异酞酸连接而成的二维双层状结构,该二维层通过氧键延伸为三维超分子结构.荧光测试研究表明配合物1具有典型的稀土铽离子绿色荧光.%A 3d-4f coordination polymer {[NiTb2(INAIP)4(H2O)6]· 8H2O}n (1) was obtained by hydrothermal assembly of NiSO4·6H2O and Tb(NO3)3·6H2O with the H2INAIP ligand.Complex 1 crystallizes in triclinic,space group P-1 with a=1.009 72(5) nm,b=1.083 43(5) nm,c=2.983 63(14) nm,V=3.209 3(3) nm3,Z=2,C56H60NiTb2N8O34,Mr=1765.67,Dc.=1.827 g· cm-3,μ=2.575 mm-1,F(000)=1 764,Rint=0.031 5,R=0.052 5,wR=O.131 8.Single-crystal X-ray diffraction analysis reveals that each INAIP2- ligand uses its two carboxyl groups to connect two/three Tb(Ⅲ)centers,and the Ni(Ⅱ) only bonds to one pyridyl group and terminal water molecules,forming a two-dimensional (2D) bilayer.On the other hand,the 2D layers are further connected by hydrogen bonding interactions to give a three-dimensional (3D) supramolecular structure.The complex 1 at room temperature shows typical green photoluminescence of rare earth Tb3+ ion.
