Abstract
Optical observation of domain structure, differential thermal analysis, dielectric and dilatometric measurements of (CH 3 NH 3 ) 4 InCl 7 have been carried out over a temperature range from 25°C to 200°C. It has been found that the crystal undergoes phase transitions at 194°C ( T 1 ) and 190°C ( T 2 ), and is ferroelastic below T 1 . Taking account of the strain-compatibility relations for domain boundaries, it is suggested from the result of optical observation that the crystal symmetry is m m m , 2/ m and 2/ m in order of descending temperature.
