The LixMPS3 (M = first row transition-metal) lamellar intercalation compounds, together with the corresponding host structures, have been studied using ESR and, as far as the iron-containing materials are concerned, Mössbauer spectroscopy. The results can be interpreted assuming that the reduced metallic sites in the intercalates are markedly segregated so that two kinds of microdomains are formed. One of them exhibits unchanged MPS3-type properties.
