摘  要:由溶剂热法合成了一种新型混核化合物{[CuTb2(INAIP)3(HCOO)(H2O)3].3H2O}n(1)(INAIP=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,P1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三维二重贯穿结构。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 new 3d-4fcoordination polymer {[CuTb2(INAIP)3(HCOO)(H2O)3]· 3H2O}, (1) was obtained by solvothermal assembly of CuCl2·2H2O and Tb(NO3)3·6H2O with the H2INAIP (5-(isonicotinamido)isophtbalic acid)ligand. Complex 1 crystallizes in triclinic, space group P1 with a=1.088 79(16) nm, b=1.518 5(2) nm, c=1.565 3(2) nm, V=2.338 1(6) nm^3, Z=2, C43H37CuTb2N6O23, Mr=1387.17, Dc= 1.970 g. cm^-3,μ=3.538 mm^-1, F(000)= 1360, Rint=0.021 2, R=0.058 9, wR=0.129 2. Single-crystal X-ray diffraction analysis revealed that each INAIP2- ligand uses its two carboxyl groups to connect two or three Tb(Ⅲ) ions into 2D lanthanide hi-layer structure. Then the 2D layers are further connected by pyridyl groups to give a three-dimensional (3D) pillared-layer structure. In addition, the luminescent property of complex 1 has been investigated at room temperature, and showed the obviously green photoluminescence in it. CCDC: 881422.
