A new 1D coordination polymer, [Cd2(L1)2(L2)2]·H2O (1, H2L1 = 4-(carboxy-methoxy)benzoic acid and L2 = 2-(4-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline), has been hydrothermally synthesized and characterized by elemental analysis and single-crystal X-ray diffraction. It crystallizes in triclinic, space group Pī with a = 9.985(5), b = 10.768(5), c = 12.512(5), α = 68.959(5), β = 80.354(5), γ = 79.663(5)°, V = 1227.4(10) 3, Z = 1, C56H36Cd2F2N8O11, Mr = 1259.73, Dc = 1.704 g/cm3, F(000) = 630, μ(MoKa) = 0.949 mm-1, R = 0.0261 and wR = 0.0655. The L1 anions link the neighboring Cd(II) atoms to form a 1D double chain structure. The L2 ligands are alternately located on both sides of the double chains. More interestingly, the lateral L2 ligands from adjacent double chains are paired to furnish strong π-π interactions, yielding a 2D supramolecular layer. N-H···O, O-H···N and O-H···O hydrogen bonds further stabilize the structure of 1. The luminescent property of 1 was studied in solid state at room temperature.
A new 1D coordination polymer, [Cd2 (L1) 2 (L2) 2] H2O (1, H2L1 = 4- (carboxy-methoxy) benzoic acid and L2 = 2- 5-f] [1,10] phenanthroline), has been hydrothermally synthesized synthetically by elemental analysis and single-crystal X-ray diffraction.

The L2 ligands are alternately located on both sides of the double chains. More interestingly, the lateral L2 ligands from adjacent double chains are paired to provide strong π-π interactions, yielding a 2D supramolecular layer. NH ··· O, OH ··· N and OH ··· O hydrogen bonds further stabilize the structure of 1. The luminescent property of 1 was studied in solid state at room temperature.
