Vibrational spectra and structure of crystalline potassium perthiocarbonate–methanol K2CS4, CH3OH

Abstract

The i.r. and Raman spectra of polycrystalline K2CS4, CH3OH and K2CS4, CH3OD addition compounds have been investigated in the 4 000–50 cm–1 range. Most of the intramolecular fundamentals have been assigned and the spectroscopic and X-ray diffraction data are correlated. The hydrogen bonded CH3OH molecules are characterized by 3400 and 3240 cm–1 OH stretching frequencies corresponding to OH ⋯ O and OH ⋯ S interactions, respectively. The valence force field determined for the two nonequivalent CS42– anions gives four different C–S stretching force constants varying from 3.4 to 4.2 mdyn Å–1 and consistent with the C–S distances; however, no C[double bond, length half m-dash]S double bond is expected from the spectroscopic data.
