Abstract
The mass spectra and appearance potentials for the major ions from Ni(CO)4, Fe(CO)5, Cr(CO)6, Mo(CO)6, W(CO)6, and V(CO)6 have been measured. Heats of formation have been calculated for 39 ions of the type M(CO)n+, where M = Ni, Fe, Cr, Mo, W, and V. The mean metal–carbon bond dissociation energies have been calculated for both the neutral molecules and the parent ions. From a comparison with the available thermochemical data for the neutral molecules it is concluded that the mean vanadium–carbon bond dissociation energy is 28 kcal/mole and the heat of formation of V(CO)6 vapor is − 204 kcal/mole.Keywords
