Abstract
Spontaneous changes of linear birefringence in the [N(C2H5)(4)](2)SbCl 5 crystal were measured in the temperature range 200-500 K. Presence o f two phase transitions at 219 K (monoclinic to orthorhombic) and at 3 47 K (orthorhombic to tetragonal) was confirmed. Two new phase transit ions were found: -at 438 K (tetragonal to tetragonal) and at 467 K -to cubic phase.
