The pseudo-one-particle potential for Cu 1 in CuCrP 2 S 6 was calculated from the room temperature (RT) structural model and shown to have a double-well shape straddling the center of the CuS 6 octahedron. It is argued that this finding supports the thermal hopping interpretation of the RT copper disorder in this compound.
