摘　　要：A novel compound, {[Cu2（nbdc）2（4,4＇-bpy）2（H2O）2]·2H2O}n（H2nbdc = 4-nitrobenzene-1,2-dicarboxylic acid, 4,4＇-bpy = 4,4＇-bipyridine）, was hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis（TGA）, and single-crystal X-ray diffraction. The complex is of orthorhombic system, space group Pbcn with a = 32.222（7）, b = 7.8503（16）, c = 28.389（6）, V = 7181（3）3, Dc = 1.720 g/cm3, Mr = 929.74, Z = 8, F（000） = 3792, μ = 1.273 mm-1, the final R = 0.0591 and wR = 0.1378 for 4548 observed reflections with I 〉 2σ（I）. The compound exhibits a 3D self-penetrating framework with bcu net topology, in which the（46·48）-networks are joined by the H2nbdc and 4,4＇-bpy linkers.A novel compound, {[Cu2（nbdc）2（4,4＇-bpy）2（H2O）2]·2H2O}n（H2nbdc = 4-nitrobenzene-1,2-dicarboxylic acid, 4,4＇-bpy = 4,4＇-bipyridine）, was hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis（TGA）, and single-crystal X-ray diffraction.
