A new 3D Cd(Ⅱ) coordination polymer, [Cd2L(dpe)]n(1, H4 L = 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) ?, β = 95.723(3)o, V = 2822.7(10) ?3, Z = 8, Dc = 1.937 Mg·m-3, μ = 1.581 mm-1, F(000) = 1608, the final R = 0.0231 and w R = 0.0629 for 2239 observed reflections with I > 2σ(I). Complex 1 is a 3D pillared bilayer(4,5,7)-connected net with the Schl?fli symbol of(414·67)(42·65·83)(44·62) topology. The photoluminescent property of 1 is also investigated.
