The heat capacity and parameters of the solid-to-solid phase transition of adamantane were measured in the temperature range (80 to 370) K using adiabatic calorimetry. The thermodynamic functions for the compound in the crystalline and liquid states were calculated. Standard molar enthalpy of formation in the crystalline state for adamantane was obtained from combustion calorimetry using two different combustion calorimeters. Available data on the enthalpy of combustion, saturated vapor pressure and enthalpy of sublimation of adamantane have been collected, analyzed and selected. Based on spectroscopic data and results of quantum-chemical calculations, the ideal-gas properties for adamantane were calculated by the statistical thermodynamics method.
