Abstract :
A study of the C60–S system in the 220–773 K range revealed the existence of only one molecular compound, monoclinic C60·2S8, that melts peritectically at 543 K (ΔπH=+54 J g−1). Although C60·2S8 forms with a negative excess volume, the enthalpy associated with its desulphuration is close to that of the sublimation of pure sulphur. The molar fractions of the peritectic and eutectic liquids were found to be xS8=0.988 (543 K) and 0.992 (385 K), respectively.
