The synthesis, structure and photoluminescence property of a novel 3D supramolecular compound based on mixed ligands of 8-hydroxyquinoline-5-sulfonate and ethylenediamine

Abstract

A new organic-inorganic hybrid coordination compound ZnQS(en) ·2H2O (1) in which two different organic ligands, ethylenediamine (en) and 8-hydroxyquinoline-5-sulfonic acid (H2QS) 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.
