摘      要：A new 3D Cd（II） coordination polymer, [Cd2L（dpe）]n （1, HaL = 6,6＂-dinitro-2,2＂,4, 4＂-biphenyltetracarboxylic acid, dpe = 1,2-di（4-pyridyl）ethylene）, has been synthesized using the hydrothermal method and characterized by single-crystal X-ray diffraction, elemental analysis, IR, thermogravimetric analysis, and photoluminescent analysis. Complex 1 crystallizes in the monoclinic system, space group C2/c with a = 8.0006（15）, b = 23.900（5）, c = 14.836（3） A, fl = 95.723（3）°, V = 2822.7（10） A3, Z = 8, Dc = 1.937 Mg.m3, p = 1.581 mm-1, F（000） = 1608, the final R = 0.0231 and wR = 0.0629 for 2239 observed reflections with I 〉 2a（/）. Complex 1 is a 3D pillared bilayer （4,5,7）-connected net with the Schlfli symbol of （4^14·6^7） （4^2·6^5·8^3） （4^4·6^2） topology. The photoluminescent property of 1 is also investigated.
