摘要：A new coordination complex [In（pda）1.5（bpy）]_n（1, H₂pda = 1,4-phenylenediacetic acid, bpy = 2,2?-bipyridine） has been synthesized under hydrothermal conditions and characterized by IR spectrum, elemental analysis, PXRD and single-crystal X-ray diffraction analysis. Crystal data for the title complex are as follows: monoclinic system, space group P21/n with a = 11.8015（7）, b = 15.9551（10）, c = 11.8858（8） ?, β = 94.844（6）o, V = 2230.0（2） ?³, Mr = 559.25, Z = 4, F（000） = 1124, Dc = 1.666 g/cm3, μ（Mo Kα） = 1.106 mm-1, R = 0.0269 and wR = 0.0569 for 4534 observed reflections with I > 2σ（I）. Complex 1 displays a 3D supermolecular structure based on the 1D zizag chains. Fluorescence spectrum measurement indicates that complex 1 shows strong fluorescence emission with a maximum peak at 447 nm in the solid state at room temperature.
