Abstract The solid state i.r. and the solid an molten state Raman spectra of the cage compound P4S10 have been recorded. An assignment of the vibrational frequencies, mainly based on polarization data, is proposed. For P4S10 an improved preparation method is reported. During melting the P4S10 units remain unchanged but partly lose terminal sulfur. Thermic decomposition reactions are given. They are reversible.

The vibrational spectra of the cage compounds P4S3, P4Se3 and AS4S3 have been recorded in the solid and the molten state. The vibrational spectra of crystalline As4Se3, which decomposes during melting, have been investigated. The frequencies wore assigned using the concept of group frequencies.A new assignment of the Raman frequencies is proposed for P4S3 based on new po­larization data. The frequencies of the arsenic compounds are reported for the first time. The Raman spectra of the molten compounds suggest that the cage structure is retained in the molten state.
