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.

Graphical abstract

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.

期刊介绍： Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
