摘要
A new coordination polymer, {[CdL(en)]center dot DMF}(n) (1, H2L = 4-[(8-hydroxy-5-quinolinyl)azo]-benzenesulfonic acid, en = ethylenediamine, DMF = N,N-dimethylformamide), has been solvothermally synthesized and structurally characterized by single-crystal X-ray diffraction, infrared (IR) spectra, elemental analysis, powder X-ray diffractions (PXRD) and thermogravimetric analysis (TGA). Compound 1 crystallizes in monoclinic, space group P2(1)/c with a = 14.6525(9), b = 13.3917(9), c = 11.8838(8) angstrom, beta = 101.2290(10)degrees, V = 2287.2(3) angstrom(3), Z = 4, C20H24CdN6O5S, M-r = 572.91, D-c = 1.664 mg.mm(-3), F(000) = 1160, mu = 1.091 mm(-1), R = 0.0232 and wR = 0.0587 for 3597 observed reflections (I > 2 sigma(I)). Compound 1 exhibits a one-dimensional (1D) double-chain structure which is further connected through hydrogen bonding and pi-pi interactions into a three-dimensional (3D) supramolecular network. In addition, it exhibits blue fluorescence at room temperature in the solid state.
