Hydrothermal reaction of naphthalene-1,8-dicarboxylate with PbCl2 leads to a new coordination polymer compound, Pb(C12H6O4). Single-crystal X-ray diffraction analysis reveals that it crystallizes in monoclinic, space group P2(1)/c with a = 13.1648(18), b = 5.3881(8), c = 14.599(2) angstrom, = 95.759(2)degrees, V = 1030.3(3) angstrom(3), Z = 4, M-r = 384.32, D-c = 2.7167 g/cm(3), F(000) = 768, mu(MoK alpha) = 16.37 mm(-1), R = 0.043 and wR = 0.097. The structure of Pb(C12H6O4) was refined by two components non-merohedral twinning model with the twin law of (-1 0 0 0 -1 0 0.224 0 1) and twinning ratio of 0.736:0.264. In this structure, the Pb atoms are surrounded by five O atoms from ligands into PbO5 polyhedra, which are further interconnected to form a 2D layer structure parallel to the bc-plane.
