摘　　要：A new complex, [Zn2（HL）2（2,5-OH-pbda）]n（1, L = 1-（1 H-imidazol-4-yl）-4-（4 Htetrazol-5-yl）benzene（H2L） and 2,5-OH-H2 pbda = 2,5-dihydroxy-terephthalic acid）, has been hydrothermally prepared and characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis and PXRD. Complex 1 crystallizes in monoclinic, space group P21/n with a = 8.8101（10）, b = 17.105（2）, c = 9.4014（11）A, β = 105.704（2）o, V = 1363.9（3） A3, Z = 4, C（14）H9N6O3Zn, Mr = 374.64, Dc = 1.824 g/cm3, μ = 1.831 mm^（-1）, S = 1.042, F（000） = 756, the final R = 0.0309 and w R = 0.1003 for 3130 observed reflections（I 2σ（I））. The H2L ligand was deprotonated to be an HL-anion, and coordinated with Zn^（2＋） to form two-dimensional（2D） Zn2（HL^-）2^（2＋） sheets, which were pillared by the 2,5-OH-pbda2-ligands to form a three-dimensional（3D） dmc net with Point（Schlafli） symbol of（4·82）（4·85）. The large vacancy of the dmc net is filled via mutual interpenetration of another independent framework, leading to the formation of a 2-fold interpenetrating architecture. Solid state luminescent property of 1 has been investigated.A new complex, [Zn2（HL）2（2,5-OH-pbda）]n（1, L = 1-（1 H-imidazol-4-yl）-4-（4 Htetrazol-5-yl）benzene（H2L） and 2,5-OH-H2 pbda = 2,5-dihydroxy-terephthalic acid）, has been hydrothermally prepared and characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis and PXRD.
