摘　　要：A one-dimensional(1 D) coordination polymer, [Cd2(TFBPDC)2(ad)2(CH3 OH)2]n(1), based on the 3,3’,5,5’-tetrafluorobiphenyl-4,4’-dicarboxylate(TFBPDC2-) and adenine(ad) ligands, was synthesized. Compound 1 crystallizes in the triclinic system, space group P1 with a = 9.7067(3), b = 9.9501(3), c = 11.6903(4) ?, α = 93.036(3), β = 107.793(3), γ = 107.107(3)°, V = 1014.77(6) ?3, Z = 2, C40H26F8N10O10Cd2, Mr = 1183.51, Dc = 1.937 g/cm3, μ = 1.160 mm-1, F(000) = 584, the final R = 0.0284 and wR = 0.0635 for 3791 observed reflections with Ⅰ> 2s(I). In 1, a pair of adenine(ad) ligands bridge two octahedrally coordinated Cd(Ⅱ) atoms to form a dinuclear [Cd2(ad)2] unit, which is linked by TFBPDC2- to generate a 1 D double chain. The neighboring chains are connected by N-H×××O hydrogen bonds to give a two-dimensional(2 D) layer, which is further linked by the O-H×××N hydrogen bonds to give a three-dimensional(3 D) supramolecular framework. IR spectrum, thermogravimetric analysis, and powder X-ray diffraction of 1 were provided. Compound 1 shows luminescent emission.
