摘　　要：One new pillared layered zinc hydroxide {Zn4（OH）6（ndc）·2（H2 O）}n,（H2 ndc =2,6-na-phthalenedicarboxylic acid） has been achieved under hydrothermal conditions by using2,6-na-phthalenedicarboxylic acid, 2,4-diami-6-phenyl-1,3,5-triazine as well as Zn（OAc）2·2 H2 O,and structurally characterized by X-ray single-crystal diffraction, IR spectra, elemental analysis,powder X-ray diffraction（PXRD） and thermogravimetric analysis（TGA）. The X-ray single-crystal diffraction proves that the title compound is in monoclinic system, space group P21/c with a =16.362（8）, b = 9.324（5）, c = 5.364（3） ?, β = 99.081（9）°, V = 808.1（7） ?3, Dc = 2.522 g/cm3, Mr =613.73, Z = 2, F（000） = 608, μ = 5.935 mm-1, GOOF = 1.050, R = 0.0469 and wR（Ⅰ > 2σ（Ⅰ）） =0.1291. In the title compound, the tetrahedral and octahedral zinc atoms are connected by μ3-OH groups to form zinc hydroxide inorganic layers extending parallel to the bc-plane. The adjacent layers are pillared by the connection of Zn2 atoms with ndc2-ligands to construct a three-dimensional（3D） structure; meanwhile, the interactions of five hydrogen bonds make the 3D network structure more stable. Furthermore, the title compound exhibits luminescent property at solid state.
