| Abstract: A novel pyridyl-dicarboxylate Schiff-base ligand (5-((pyridin-3-ylmethyl)amino)isophthalic acid, H2L) and its Zinc(Ⅱ) complex, namely, ZnL (1), were synthesized. The ligand was characterized by NMR analysis. The X-ray crystallographic analysis on complex 1 shows that 1 crystallizes in homoclinic, space group P21/c with a=0.753 83(10) nm, b=1.040 52(14) nm, c=1.734 67(19) nm, β=112.123(5)°, V=1.260 5(3) nm3, Z=4, Dc=1.769 g· cm-3, F(000)=680, μ=1.966 mm-1, the final R=0.030 8, wR=0.085 6. In complex 1, the coordination environment of Zn(Ⅱ) is distorted tetragonal-pyramid with N1O4 set. The 2D 4,4-topological sheets in 1 packed along a axis to form its 3D framework, which was stabilized by the π…π interactions between the adjacent aromatic rings on the neighbouring sheets. The photoluminescent property of 1 was also investigated. CCDC: 769437 |
