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-imidazo [4,5-f] [ 1,10]phenanthroline (L). Crystallographic data for the compound: triclinic, space group Pi with a = 8.777(2), b = 10.662(2), c = 13.799(3) A, a = 89.480(4), β = 73,933(3), γ = 81.980(4)°, V = 1228.2(5) A3, Z = 2, C27H22.50FN4NiO5.25, Mr = 568.70, Dc = 1.527 g/cm3, F(000) = 583,μ(MoKα) = 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.
