✦ Synopsis
Polythermal investigation of the C6o-CC14 system resulted in two phase diagrams. The stable one involves two solvates with 1 : 12 and 1 : 2 molar ratios, respectively. A metastable diagram, only showing the 1 : 2 solvate, has been observed. C6o, 12 CCI 4 and C6o, 2 CC14 decompose peritectically at 299 and 402 K, with AH= 15.2 and 61 J g-l, respectively. C6o, 12 CCI 4 is formed with a positive excess volume while C60, 2 CC14 does so with a negative one. The desolvation enthalpy for C6o, 2 CCI 4 and sublimation enthalpy for pure CC] 4 are close.

The radical cation of C6o is generated either via hole transfer from the radical cation of CCI 4 to C6o or via electron transfer from triplet C6o to CC14. The radical adduct of "CC13 to C6o, [C6oCC13]" , was also produced via two different mechanisms, namely the radical addition reaction and the rea
