摘要A one-dimensional (1D) coordination polymer, [Cd2(TFBPDC)2(ad)2(CH3OH)2]n (1), based on the 3,3΄,5,5΄-tetrafluorobiphenyl-4,4΄-dicarboxylate (TFBPDC2–) and adenine (ad) ligands, was synthesized. Com- pound 1 crystallizes in the triclinic system, space group P with a = 9.7067(3), b = 9.9501(3), c = 11.6903(4) Å, α = 93.036(3), β = 107.793(3), γ = 107.107(3)°, V = 1014.77(6) Å3, 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 > 2(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 1D double chain. The neighboring chains are connected by N–HO hydrogen bonds to give a two-dimensional (2D) layer, which is further linked by the O–HN hydrogen bonds to give a three-dimensional (3D) supramolecular framework. IR spectrum, thermo- gravimetric analysis, and powder X-ray diffraction of 1 were provided. Compound 1 shows luminescent emission.
