摘　　要：A new metal-organic coordination compound framework formulated {[Pb(PTCP)(2,5-pydc)]2·H2O}n (1) (PTCP=2-phenyl-1H-1,3,7,8-tetraazacyclopenta[l]-phenanthrene, H2pydc=pyridine-2,5-dicarboxylic acid) has been prepared in the hydrothermal condition and characterized by single-crystal X-ray diffraction, elemental analysis, IR and TG. It crystallizes in monoclinic, space group C2/c with a=2.129 2(4) nm, b=1.111 2(2) nm, c=2.049 4(4) nm, β=105.02(3)°, V=4.683 2(16) nm3, Z=4, Pb2C52H32N10O9, Mr=1 355.26, Dc=1.922 g·cm-3, F(000)=2 600, S= 0.825, R1=0.056 2 and wR2=0.168 9. In the crystal, the Pb atom is five-coordinated by three N and two O atoms. The complex forms a one-dimensional zigzag polymeric chain along the b axis which is stacked to furnish a two- dimensional supramolecular layer structure via aromatic π-π interactions in the ab plane. In addition, hydrogen bonds are observed in the compound which play an important role in forming the final structure. Solid-state fluorescence spectrum of 1 exhibits the maximum emission peak at 621 nm.A new metal-organic coordination compound framework formulated {[Pb（PTCP）（2,5-pydc）]2·H2O}n （1） （PTCP=2-phenyl-1H-1,3,7,8-tetraazacyclopenta[l]-phenanthrene, H2pydc=pyridine-2,5-dicarboxylic acid） has been prepared in the hydrothermal condition and characterized by single-crystal X-ray diffraction, elemental analysis, IR and TG.
