Two lead(Ⅱ)compounds,[Pb(qlc)(phen)2(NO3)]2·H2O(1)and[Pb(qlc)2(phen)]·3H2O(2)(Hqlc=quinoline-3-carboxylic acid,phen=1,10-phenanthroline),were synthesized and characterized by elemental analysis,single-crystal X-ray diffraction,IR and thermogravimetric analysis.Crystal 1 is of monoclinic,space group C2/c with a=25.246(5),b=12.543(3),c=18.917(4),β=105.77(3)o,V=5765(2)3,Z=4,C68H46N12O11Pb2,Mr=1621.53,Dc=1.886 g·cm-3,μ(MoKα)=5.912 mm-1,F(000)=3152,GOOF=1.080,the final R=0.022 and wR=0.0571 for 4822 observed reflections(I>2σ(I)).Crystal 2 is of triclinic,space group P1 with a=8.7883(10),b=11.7031(13),c=15.9320(17),α=69.9400(10),β=78.9780(10),γ=79.1650(10)o,V=1497.4(3)3,Z=2,C32H26N4O7Pb,Mr=785.71,Dc=1.729 g·cm-3,μ(MoKα)=5.688 mm-1,F(000)=756,GOOF=1.106,the final R=0.0313 and wR=0.088 for 5915 observed reflections(I>2σ(I)).Single-crystal X-ray diffraction analysis reveals that 1 exhibits a two-dimensional(2D)layer based onπ-πstacking interactions between phen.Simultaneously,the adjacent 2D layers are assembled viaπ-πstacking interactions between phen and quinoline rings into a 3D supramolecular structure.The zerodimensional structure of 2 is also further extended byπ-πinteractions to form a 2D supramolecular layer.Furthermore,these two compounds exhibit photoluminescence at room temperature in the solid state and their photocatalytic activities have been studied by degradation methylene blue.

Crystal 2 is of triclinic, space group P1 with a = 8.7883 (10), b = 11.7031 (13), c = 15.9320 (17), α = 69.9400 (10), β = 78.9780 (10), γ = 79.1650 (10) o, V = 1497.4 3 = 3, Z = 2, C32H26N4O7Pb, Mr = 785.71, Dc = 1.729 g · cm-3, μ MoKα = 5.688 mm-1, F000 = 756, GOOF = 1.106, the final R = 0.0313 and Single-crystal X-ray diffraction analysis reveals that 1 exhibits a two-dimensional (2D) layer based on π-π stacking interactions between phen. Simultaneously, wR = 0.088 for 5915 observed reflections (I> the adjacent 2D layers are assembled viaπ-πstacking interactions between phen and quinoline rings into a 3D supramolecular structure. The zerodimensional structure of 2 is also further extended byπ-πinteractions to form a 2D supramolecular layer.
