Thermochemistry of Gaseous Compounds of Metals.
Abstract
The gaseous molybdenum fluorides were studied by high temperature mass spectrometry, using both equilibrium and electron impact techniques. A number of electron impact processes were studied, including positive ion formation by simple and dissociative ionization, and negative ion formation by dissociative electron capture. The results of these studies were used to derive the standard heats of formation, bond dissociation energies and ionization potentials of gaseous MoF, MoF2, MoF3, MoF4, and MoF5. In addition, tentative values for the electron affinities of MoF4, MoF5, and MoOF3 were derived. The results begin to give some insight into differences in chemical bonding and electronic structure between transition and nontransition metal fluorides.
