摘　　要：The title complex, [Zn3（L）2（H2 O）2]n（1, H3 L = 5-（（3-formylphenoxy）methyl）isophthalic acid）, has been synthesized under hydrothermal conditions and structurally characterized by single-crystal X-ray diffraction, IR spectroscopy and thermogravimetric analysis. Compound 1 exhibits a 3D binodal（4,8）-connected net based on trinuclear [Zn3（COO）4] clusters with the topology symbol of（416·612）（44·62）2. It crystallizes in monoclinic system, space group P21/c, with a = 13.548（3）, b = 13.291（3）, c = 8.2750（1） ？, β = 97.08（3）°, V = 1478.7（6） ？3, Z = 2, Mr = 858.6 g/mol, Dc = 1.928 mg/m3, μ = 2.49 mm-1, F（000） = 864, GOOF = 1.12, the final R = 0.0457 and wR = 0.1329 for 4334 observed reflections with I 〉 2σ（I）. Additionally, the photoluminescent behaviours of 1 and H3 L have also been investigated in the solid state at room temperature.The title complex, [Zn3（L）2（H2 O）2]n（1, H3 L = 5-（（3-formylphenoxy）methyl）isophthalic acid）, has been synthesized under hydrothermal conditions and structurally characterized by single-crystal X-ray diffraction, IR spectroscopy and thermogravimetric analysis.
