| Abstract: A coordination polymer, [Pb2(L)(1,4-NDC)2]·0.5H2O (1) (L=1-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)naphthalen-2-ol and 1,4-H2NDC=1,4-naphthalenedicarboxylic acid) has been hydrothermally synthesized and characterized by elemental analysis, IR, thermogravimetric analysis (TGA), and single-crystal X-ray diffraction. It crystallizes in triclinic system, space group P1 with a=0.950 78(6) nm, b=1.265 11(8) nm, c=1.785 91(12) nm, α=78.441(2)°, β=78.620(1)°, γ=77.124(1)°, V=2.025 3(2) nm3, In compound 1, the 1,4-NDC ligands bridged the neighboring Pb(Ⅱ) atoms to yield a two-dimensional layer structure. The π-π stacking interactions between L ligands extended the adjacent layers into a two-dimensional supramolecular double layer. The N-H…O hydrogen bond further stabilizes the structure of 1.
