摘要

A novel coordination polymer, [Pb(1,3-pda)(H2O)](n) (1) (1,3-pda = 1,3-phenylenediacetic acid), was hydrothermally synthesized and characterized by elemental analysis, FT-IR spectroscopy, and X-ray single-crystal diffraction. Compound 1 crystallizes in orthorhombic, space group P2(1)2(1)2(1) with a = 7.3259(7), b = 9.0626(9), c = 16.6368(16) angstrom, C10H10NO5Pb, M-r = 417.37, V = 1104.55 (19) angstrom(3), Z = 4, D-c = 2.510 g.cm(-1), S = 1.069, R = 0.0458, and wR = 0.1155 (I > 2 sigma(I)). Single-crystal X-ray diffraction analysis reveals that compound 1 is a novel 3D complicated framework resulting from the interweaving of 1D rod-shaped [Pb(COO)(2)O](n) chains and [Pb(pda)](n) helical chains. Topological analysis suggests that compound 1 features a uninodal 4-connected sra net with the point symbol of (4(2).6(3).8). Solid-state properties, such as photoluminescence and thermal stability of 1, have also been investigated. Keywords: Pb(II)-compound, 1, 3-phenylenediacetic acid, topological structure, fluorescent property
