Title: Synthesis and Structure of a Two-Dimensional Pb(II),Coordination Polymer with Naphthalenedicarboxylic Acid and Phenanthroline Derivative Ligand
Abstract: A coordination polymer,[Pb2(L)(1,4-NDC)2]·0.5H2O(1)(L=1-(1H-imidazophenanthrolin-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.
