Dielectric properties of CuInP2S6 layered crystals in the range of ferrielectric phase transition are studied under hydrostatic pressure. The pressure dependence of the phase transition temperature testifies to the phase transition being of the order/disorder type. The (p,T) phase diagram of CuInP2S6 crystals has been constructed.

Key words: phase transitions, ferrielectrics, pressure, dielectric properties
