Organometallic intercalates of some lamellar metal phosphorus trisulphides

Abstract

The lamellar compounds MPS₃(M = Mn, Zn, Fe, or Ni) have been shown to react with neutral [Co(η-C₅H₅)₂] and [Cr(η-C₆H₆)₂] forming the intercalates of general stoicheiometry MPS₃[Co(η-C₅H₅)₂]_x and MPS₃[Cr(η-C₆H₆)₂]_x. The role of the solvent is quite important. Thus, MnPS₃ intercalates [Cr(η-C₆H₆)₂] together with benzene forming MnPS₃[Cr(η-C₆H₆)₂]_0.24(C₆H₆)_0.10. The compounds MnPS₃ and ZnPS₃ have also been shown to take up cationic species, giving the related intercalation products; this unexpected route to intercalation is briefly discussed.
