| Abstract: A new 3d-4f coordination 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=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 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. |
