Abstract

The Raman and IR spectra of [(C3H7)2NH2]3ClSnCl6 have been obtained at room temperature. The vibrational bands of cations in this salt show that the latter are distorted from C2v symmetry and are strongly hydrogen-bonded to the respective anions. Combinations and overtones bands intensified by Fermi Resonance were observed between 1700 and 2800 cm-1 region of the Infrared spectrum of this compound. The Raman spectrum of anions can be interpreted in terms of disordered groups not clearly showing the predicted splitting of bands.

Keywords : Dipropylamonium hexaclorostannate chloride; DTA; Raman and Infrared spectra.
