摘　　要：A unique metal-organic framework [Cd2（L）1.5（μ3-OH）（H2 O）2 ]·2H2 O（1, H2 L = 2,5-dibenzoylterephthalic acid） has been synthesized under hydrothermal conditions, and characterized by single-crystal X-ray diffractions, elemental analyses, IR spectra and fluorescence spectrum. The compound is of triclinic system, space group P1, C33 H27 CdO14, Mr = 870.33, a = 12.2939（17）, b = 12.5135（9）, c = 13.2046（10）, α = 115.3190（10）, β = 96.9140（10）, γ = 109.7950（10）°, V = 1641.6（3）3, Z = 2, Dc = 1.761 g/cm3, F（000） = 862, μ（MoK） = 1.366 mm-1, Rint = 0.0148, R = 0.0240 and wR = 0.0639 for 5995 observed reflections with I 〉 2σ（I）. X-ray analysis shows that the title complex exhibits a 3D framework with（412·63） topology, in which the tetra-nuclear [Cd4（μ3-OH）2 ] clusters act as 6-connected nodes, and the L ligands can be simplified to be linear connectors. Moreover, the thermal stability and fluorescence have been studied in detail.A unique metal-organic framework [Cd2（L）1.5（μ3-OH）（H2 O）2 ]·2H2 O（1, H2 L = 2,5-dibenzoylterephthalic acid） has been synthesized under hydrothermal conditions, and characterized by single-crystal X-ray diffractions, elemental analyses, IR spectra and fluorescence spectrum.
