| Abstract: A coordination polymer, [Co2(L)2(1,5-PDC)2]·0.5H2O 1 (L=2-(2-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline and 1,5-PDC=pentane-1,5-dicarboxylate, has been synthesized under hydrothermal condition, and characterized by elemental analysis, IR spectroscopy, TGA, UV-vis spectrum and single-crystal X-ray diffraction. Crystal data: C104H86Co4F4N16O17, triclinic system, space group P1, a=1.108 2(5) nm, b=1.390 2(4) nm, c=1.601 7(6) nm, α=90.806(5)°, β=93.429(3)°, γ=111.312(5)°, V=2.293 0(15) nm3, Z=1, R=0.059 7, wR=0.160 8. In 1, the 1,5-PDC ligand bridges neighboring Co(Ⅱ) atoms to form a one-dimensional (1D) chain structure. The π-π interactions between neighboring chains resulted in a 2D supramolecular architecture. In addition, the N-H…O and O-H…N hydrogen-bonding interactions further stabilize the supramolecular structure of 1. CCDC: 872031. |
