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.
