✦ Synopsis

The DSC method was used to find the phase transitions in crystals C6OF36 and C60F48 at 370 K and 315 K, respectively.

The phase transitions disappear when the samples under study are treated mechanically, correlating with earlier data concerning the effect of mechanical treatment on the properties of low-and high-temperature phases of C60 and as a result on the orientation phase transition (260 K). When studying the crystal phase of fullerenes and their derivatives, it is necessary to allow for the structural hypersensitivity.
