The Synthesis, Structure And Photoluminescence Property Of A Novel 3d Supramolecular Compound Based On Mixed Ligands Of 8-Hydroxyquinoline-5-Sulfonate And Ethylenediamine

A new organic-inorganic hybrid coordination compound ZnQS(en)center dot 2H(2)O (1) in which two different organic ligands, ethylenediamine (en) and 8-hydroxyquinoline-5-sulfonic acid (H(2)QS) coordinate with zinc ions, has been synthesized via the evaporation method and characterized by single crystal X-ray diffraction analysis, IR spectroscopy and thermogravimetric analysis (TGA). The structure solution showed that compound 1 displays a three-dimensional supramolecular network by synergic linkage of hydrogen and coordinated bonds. Moreover, compound 1 exhibits intense photoluminescence at 513 nm excited at 396 nm in the solid state at room temperature.
