An ESR investigation of a cation-exchange intercalation reaction in Cd₂P₂S₆

Cd₂P₂S₆ crystallizes in a layered structure that is readily intercalated with a variety of chemical species. In many instances, intercalation of ions results in the loss of Cd²⁺ from the host lattice. When Cd₂P₂S₆ is intercalated with pyridine complexes of Mn²⁺, cadmium ion is displaced from the host lattice. Analysis of the ESR spectra indicates that Mn²⁺ moves from interlayer sites to occupy the Cd²⁺ intralamellar lattice vacancies at elevated temperatures.
