The standard molar enthalpy of formation of C70 in the crystalline state at 298.15 K has been determined as 2577.8 ± 16.2 kJ mol-1 by microcombustion calorimetry. ΔfH0m(C70,g) at 298.15 K was also derived, using literature data for the enthalpy of sublimation, vapour pressure, solid state heat capacity and solid state entropy, in conjunction with ideal-gas phase heat capacity and entropy values calculated by Statistical Mechanics. The obtained standard molar enthalpy of formation of gaseous C70 is compared to the corresponding predictions of several theoretical methods and used to discuss the bonding energetics in the molecule.
