By using a conventional bomb calorimeter and a technique of burning pure C-60 on a gram-scale in a mini-crucible, the standard massic energy of combustion of C-60 was determined : Delta(c)u degrees = - (36036.06 +/- 6.04) J . g(-1). The corresponding thermodynamic functions at T = 298.15 K were derived for C-60 : Delta(c)H(m) degrees(cr)= - (25970.07 +/- 9.67) kJ . mol(-1), Delta(f)H(m) degrees(cr) = (2359.47 +/- 9.72) kJ . mol(-1), and Delta(f)H(m) degrees(g) = (2588 +/- 12) kJ . mol(-1). These results were compared with experimental values in the literature.
