(NH3CH3)5Bi2X11(X = C1, Br) belong to a rich family of alkylammonium halogenobismuthate crystals showing ferroelectric properties and several successive structural phase transitions (IT) [l-2]. They are characterized by the same sequence of the phases symmetry changing [1,3]. Both of them display th...
