The coordination polymer ［Pb(μ-pda)］n (1) was synthesized with pyridine-2,6-dicarboxylic acid (H2pda) and lead acetate as raw materials by room temperature solid state reaction. The composition and structure of 1 were characterized by elemental analysis, X-ray powder diffraction, X-ray single crystal diffraction and infrared spectroscopy. Its thermal stability and fluorescence properties were also studied. The single crystal structure shows that 1 belongs to monoclinic system with space group P21/n, and the cell parameters are a=0.980 84(11) nm, b=0.554 73(7) nm, c=1.433 62(16) nm and β=105.093(3)°. The molecular structure of 1 is composed of two Pb2+ and two pda2-. It contains two ［Pb(μ-pda)］ units, each Pb2+ center is coordinated with six oxygen atoms and one nitrogen atom from pda2- to form a seven coordinated single-cap triangular prism configuration. The thermal stability study shows that the thermal decomposition reaction of 1 in nitrogen atmosphere include the collapse of complex framework and the oxidative decomposition of ligand, and the final residue is PbO. The fluorescence property of 1 indicates that the coordination polymer has fluorescence, which may come from the fluorescence inside the ligand π*→π charge transition.
