Spectroscopic studies on manganese thiophosphate intercalated with cesium ions

The [Cs.sub.2x][Mn.sub.1-x]P[S.sub.3] compound is prepared by the cesium ion-exchange intercalation reaction on MnP[S.sub.3] and is characterized by various spectroscopic methods. The studies have shown that the [Cs.sup.+] intercalation process in MnP[S.sub.3] is complete and has led to the creation of intercalated vacancies.
