✦ Synopsis

The standard molar enthalpy of combustion of fluorinated fullerene C 60 F 48 was determined by rotating-bomb calorimetry, c H o m = -(24638 ± 163) kJ • mol -1 . Using this result and the standard molar enthalpy of sublimation, sub H o m = (109 ± 7) kJ • mol -1 , the values of the standard molar enthalpies of formation of C 60 F 48 in the crystalline and gaseous states were found to be -(7563 ± 166) kJ • mol -1 and -(7454 ± 166) kJ • mol -1 , respectively. The enthalpy of reaction C 60 F 48 (g) = C 60 (g) + 48F(g) was calculated, r H o m (298.15 K) = (13800 ± 167) kJ • mol -1 , or r H o m (298.15 K)/48 = (287.5 ± 3.5) kJ • mol -1 .
