| Abstract: A new 1D chain coordination polymer, [Cd2(L)2(1,3-BDC)2]n 1 (L=2-(3-fluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline and 1,3-H2BDC=1,3-benzenedicarboxylic acid) has been hydrothermally synthesized and characterized by elemental analysis, IR and single-crystal X-ray diffraction. It crystallizes in triclinic, space group P1 with a=1.080 8(4) nm, b=1.149 5(4) nm, c=1.924 8(7) nm, α=106.482(5)°, β=99.436(6)°, γ=93.093(6)°, V=2.249 2(14) nm3, Z=4, C27H15CdFN4O4, Mr=590.83, Dc=1.745 g·cm-3, F(000)=1 176, μ(Mo Kα)=1.024 mm-1, R=0.044 5 and wR=0.111 7. In compound 1, the 1,3-BDC ligands linked the adjacent Cd(Ⅱ) atoms to generate a one-dimensional chain structure. The CH-π interactions between L and 1,3-BDC extended the adjacent chains into a two-dimensional supramolecular layer. The N-H…O hydrogen bond further stabilizes the structure of 1.
