Abstract

Intercalation of Cu into layered polychalcogenide La₂O₂S₂ was demonstrated to be viable both under solvothermal conditions at 200 °C and mechanical ball milling at ambient temperature. This result evidences the soft-chemical nature of metal intercalation into layered polychalcogenides driven by the redox reactivity of anion–anion bonds.
