- Abstract
In this study, a new Co(II)-substituted Keggin-type polyoxomolybdate was synthesized at room temperature and characterized by FT-IR, powder X-ray diffraction (PXRD), UV-visible spectroscopy, TG-DTA thermal analysis, single crystal X-ray diffraction technique and cyclic voltammetry study. The crystal packing exhibits non-conventional C−H···O and C−H···S hydrogen bonds which lead to a three-dimensional supramolecular framework. The catalytic property of compound (1) was positivity tested in the degradation of crystal violet dye (CV) investigated. A new organic-inorganic compound based on Keggin anions and Cobalt (II)ions, namely [Co(C2H6OS)6]2[HPMo11O39Co(C2H6OS)].2(C2H6OS) ·2.5(H2O) (1) was synthesized and characterized by single-crystal X-Ray diffraction, IR, thermal analyses and cyclic voltammetry. The catalytic ability of (1) for decolorization of Crystal violet dye from aqueous solutions has been investigated.
