Abstract

Measurements of the enthalpy of thermal decomposition of chromium hexacarbonyl have been made using a “hot-zone” reaction calorimeter. Independent measurements of the energy of combustion of the hexacarbonyl in oxygen at 298 K by static bomb calorimetry lead to an enthalpy of formation in accord with that derived from the thermal decomposition measurements. From consideration of all the reported measurements of the enthalpy of formation of chromium hexacarbonyl, a mean selected value is proposed: ΔHof[Cr(CO)6, c] = −234.2 ± 0.4 kcal mol−1,  − 979.9 ± 1.7 kJmor−1.
