摘　　要：A coordination polymer based on the carboxylate-sulfonate ligand of biphenyl-3,3?-disulfonyl-4,4?-dicarboxylate(BPDSDC4–), namely, [DyK(BPDSDC)(H2 O)4]n(1), was synthesized and characterized. Compound 1 crystallizes in the triclinic system, space group P1 with a = 6.3950(4), b = 12.8171(9), c = 15.8005(10) ?, α = 109.5430(10), β = 90.8050(10), γ = 102.7170(10)°, V = 1185.12(13) ?3, Z = 2, C14 H14 O14 S2 KDy, Mr = 671.97, Dc = 1.883 g/cm3, μ = 3.567 mm-1, F(000) = 654, the final R = 0.0262 and wR = 0.0718 for 4408 observed reflections with I > 2?(I). In compound 1, the eight-coordinated Dy(III) and nine-coordinated K(I) ions are connected by the carboxylate and sulfonate groups as well as bridging water molecules to generate a one-dimensional(1 D) ribbon structure. The ribbons are linked by the biphenyl moieties of BPDSDC4– ligands to give a two-dimensional(2 D) double layered structure. The 2 D layers are further linked by the interlayered hydrogen bonds between the coordinated water molecules and sulfonate oxygen atoms to form a three-dimensional(3 D) packing. Compound 1 shows characteristic Dy(III) luminescence emission.
