摘要A new luminescent Cd(II) coordination polymer, [Cd(L)2(H2O)]n1 (HL = xan- thene-9-carboxylic acid), was synthesized hydrothermally and characterized by satisfactory elemen- tal analysis, FT-IR spectra and single-crystal X-ray diffraction. The crystal is of orthorhombic system, space group P212121 witha = 6.4548(4), b = 13.0876(12), c = 27.466(2) Å, V = 2320.3(3) Å3,C28H20CdO7, Mr = 580.84, Z = 4, Dc = 1.663 g/cm3, F(000) = 1168, μ = 0.990 mm-1, Flack parameter = 0.00(2), the final R = 0.0296 and wR = 0.0691 for 5301 observed reflections (I > 2σ(I)). 1 features a one-dimensional (1D) carboxylate oxygen-bridged inorganic chain, which is further connected by intermolecular hydrogen bonds into a three-dimensional (3D) framework. Moreover, compound 1 exhibits strong photoluminescence in the solid state at room temperature.
