摘要:A new Pb(Ⅱ) coordination polymer, [Pb(1,4-chdc)(L)]n·nH2O(1), was synthesized under hydrothermal condition(1,4-H2 chdc = 1,4-cyclohexanedicarboxylic acid and L = 2-(3-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline). Its crystal structure was determined by singlecrystal X-ray diffraction. Compound 1 crystallizes in triclinic, space group P1 with a = 9.1182(8), b = 11.3249(10), c = 12.7326(12) ?, α = 77.897(2), β = 81.644(2), γ = 84.491(2)°, V = 1269.0(2) ?~3, Z = 2, C27H24FN4O5Pb, Mr = 710.69, Dc = 1.860 g/cm~3, F(000) = 690, μ(MoKa) = 6.701 mm-1, R = 0.0349 and wR = 0.0746. In 1, each 1,4-chdc anion bridges two neighboring Pb(Ⅱ) atoms in a bidentate chelating coordination mode to give a chain structure. The L ligands are attached on one side of the chain through chelating the Pb(Ⅱ) atoms, and are stacked with those of an adjacent chain through π-π interactions, yielding a layer structure. The O–H···O and N–H···O hydrogen bonding interactions further stabilize the supramolecular layer structure of 1. Moreover, solid state luminescent property of 1 was also studied.
