Реферат:	eng: The sequence of phase transitions P3 ¯ m1 → C2 / m→ C2 / c in K3Na(CrO4)2 crystals and existence of the intermediate phase have been studied both experimentally by the Raman scattering method and theoretically by programs and retrieval tools of the Bilbao Crystallographic Server. A zone-edge soft mode responsible for a transition from the intermediate C2/m to a low-symmetry C2/c phase at T = 210 K has been discovered experimentally for the first time. The symmetry of the soft mode has been established theoretically to be A2 +. The temperature interval of the intermediate monoclinic phase has been determined to be 239–210 K. © 2016, Pleiades Publishing, Ltd.
