A new 3d-4fcoordination polymer {[CuTb2(INAIP)3(HCOO)(H2O)3]·3H2O}n (1) was obtained by solvothermal assembly of CuCl2·2H2O and Tb(NO3)3·6H2O with the H2INAIP (5-(isonicotinamido)isophthalic 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) nm3,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=O.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 bi-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.
