A new Pb(II)-based coordination polymer, [Pb(L)](n) (1), was hydrothermally synthesized and its structure was determined by single-crystal X-ray diffraction (H2L = octane-1,8-dicarboxylic acid). Compound 1 crystallizes in orthorhombic, space group Pnma with a = 32.061(4), b = 7.2597(8), c = 4.8084(5) angstrom, V= 1119.2(2) angstrom(3), Z = 4, C10H16O4Pb, M-r = 407.42, D-c = 2.418 g/cm(3), F(000) = 760, mu(MoKa) = 15.066 mm(-1), R = 0.0270 and wR = 0.0666. In 1, each Pb(II) cation is coordinated by six carboxylate oxygen atoms from four L2- anions. Each L2- anion bridges three Pb(II) atoms in a mu(3):eta(2):eta(1):eta(1) mode to form a 3D framework. The structure of 1 was characterized by IR spectrum and thermogravimetric analysis. Moreover, solid state luminescent property of 1 was also investigated.
