| Abstract: A new zinc coordination polymers [Zn(dib)(H2O)3]SO4·2H2O (1) was obtained by hydrothermal assembly of ZnSO4·7H2O with a isophthalic acid in the presence of N-donor ligands, namely 1,4-di(1-imidazolyl)benzene (dib). Complex 1 crystallizes in orthorhombic, space group Fddd with a=1.266 87(13) nm, b=2.269 9(2) nm, c=2.644 7(3) nm, V=7.605 1(13) nm3, Z=16, C12H20N4ZnO9S, Mr=461.75, Dc=1.613 g·cm-3, μ=1.454 mm-1, F(000)=3 808, Rint=0.040 8, R=0.043 2, wR=0.099 8. Single-crystal X-ray diffraction analysis revealed that each dib ligand in turn uses its two mizale groups to connect two metal centers, then the one-dimensional (1D) chains is formed. On the other hand, the 1D chains are further connected by hydrogen bonds interactions to give a three-dimensional (3D) supramolecular structure. In addition, the luminescent property of complex 1 has been investigated at room temperature, indicating the blue photoluminescence exists in it. CCDC: 804498. |
