摘要
A new luminescent Cd（Ⅱ） coordination polymer, [Cd（L）2（H2O）]n 1 （HL = xan-thene-9-carboxylic acid）, was synthesized hydrothermally and characterized by satisfactory elemental analysis, FT-IR spectra and single-crystal X-ray diffraction. The crystal is of orthorhombic system, space group P212121 with a = 6.4548（4）, b = 13.0876（12）, c = 27.466（2）, V = 2320.3（3）3, 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.
