A new 1D coordination polymer, [Pb(L)(cis-1,4-chdc)]·0.5H2O (cis-1,4-chdc = 1,4-cyclohexanedicarboxylate and L = 2-(4-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline), has been synthesized under hydrothermal conditions and characterized by elemental analysis, TG and single-crystal X-ray diffraction. It crystallizes in triclinic, space group P1 with a = 9.153(5), b = 10.338(5), c = 13.074(5), α = 80.956(5), β = 89.725(5), γ = 80.534(5)°, V = 1204.8(10)3 , Z = 1, C54H44F2N8O9Pb2 , Mr = 1401.35, Dc = 1.931 g/cm3 , F(000) = 678, μ(MoKa) = 7.055 mm-1 , R = 0.0277 and wR = 0.0559. Each cis-1,4-chdc anion coordinates with two Pb(Ⅱ) atoms in a bis-chelating coordination mode. In this way, cis-1,4-chdc anions bridged the neighboring Pb(Ⅱ) atoms to generate a 1D chain structure. The L ligands from neighboring chains are paired through the strong π-π interactions to generate a fascinating 2D supramolecular layer.
A new 1D coordination polymer, [Pb (L) (cis-1,4-chdc)] · 0.5H2O (cis-1,4-chdc = 1,4-cyclohexanedicarboxylate and L = 2- -imidazo [4,5-f] [1,10] phenanthroline), has been synthesized under hydrothermal conditions and characterized by elemental analysis, TG and single-crystal X-ray diffraction.

In this way, cis-1, 4-chdc anions bridged the nearby Pb chains are paired through the strong π-π interactions to generate a fascinating 2D supramolecular layer.
