| 摘 要： | A new one-dimensional Ni(II) coordination polymer Ni(L)(cis-1,4- chdc)]n?1.25nH2O has been synthesized under hydrothermal conditions by using 1,4-cyclohexanedicarboxylic acid (1,4-H2chdc) and 2-(3-fluorophenyl)-1H-imidazo4,5-f]1,10]phenanthroline (L). Crystallographic data for the compound: triclinic, space group P with a=8.777(2), b=10.662(2), c=13.799(3), α=89.480(4), β=73.933(3), γ=81.980(4)°, V=1228.2(5)3, Z=2, C27H22.50FN4NiO5.25, Mr=568.70, Dc=1.527 g/cm3, F(000)=583, μ(MoKa)=0.846 mm-1, R=0.0634 and wR=0.1465. Neighboring Ni(II) atoms are linked by the cis-1,4-chdc ligands to generate a one-dimensional chain structure. The π-π interactions between the L ligands of neighboring chains led to the formation of a two-dimensional supramolecular layer. The elemental analysis, IR spectrum and TG of the compound have been studied.
