It was found that the values of dT(0)/dP are negative for the Mg, Zn. Co. Mn trifluorides and positive for NH4CdF3 and NH4MnCl3. Comparison with the known data for other halide and oxide perovskites allowed to conclude that the sign of dT(0)/dP is correlated with the value of the Goldschmidt tolerance factor of the perovskite, and its value is closely related to the temperature and mechanism of the transition.
