Synthesis, Vibrational Spectra and Normal Coordinate Analysis of Cesium-Hexathiohypodiphosphate CS4P2S6

Abstract

The title compound has been prepared by elemental synthesis at high temperatures and also by reaction of Na4P2S6 · 6 H2O with CsCl in aqueous solution. Both reaction products have closely related vibrational spectra which are assigned on the basis of a P2[FORMULA OMITTED] anion with perturbed D3d symmetry. A normal coordinate analysis has been performed using a force field with 4 initial force constants. The refined force field, potential energy distribution (PED), mean amplitudes of vibration and Coriolis coupling constants are given. © 1985, Walter de Gruyter. All rights reserved.
