Abstract
A new coordination polymer, {[CdL(en)]·DMF}n (1, H 2L = 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 P21/c with a = 14.6525(9), b = 13.3917(9), c = 11.8838(8) Å, β = 101.2290(10)°, V = 2287.2(3) Å3, Z = 4, C 20H24CdN6O5S, Mr = 572.91, Dc = 1.664 mg·mm-3, F(000) = 1160, μ = 1.091 mm-1, R = 0.0232 and wR = 0.0587 for 3597 observed reflections (I > 2σ(I)). Compound 1 exhibits a one-dimensional (1D) double-chain structure which is further connected through hydrogen bonding and π-π interactions into a three-dimensional (3D) supramolecular network. In addition, it exhibits blue fluorescence at room temperature in the solid state.
