description

Abstract Spontaneous changes of linear birefringence in the [N(C2H5)4]2SbCl5 crystal were measured in the temperature range 200–500 K. Presence of two phase transitions at 219 K (monoclinic to orthorhombic) and at 347 K (orthorhombic to tetragonal) was confirmed. Two new phase transitions were found: -at 438 K (tetragonal to tetragonal) and at 467 K -to cubic phase.
