The oxidation state of xenon in Xenon Difluoride is +2. Xenon hexafluoride and its other forms are very strong fluorinating agents. 1968, 48 (1), 312318. The calculated vibrational frequencies for the C(3v) structure best fit the experimental frequencies. FOIA Gas-phase electron diffraction (dating from 1968) showed that the structure was approximately, but not exactly, octahedral: the experimental diffractogram differed from the theoretical diffractogram calculated for a hypothetical octahedral molecule.1 The authors considered a wide range of possible geometrical distortions, and found that $C_\mathrm{2v}$ or $C_\mathrm{3v}$ structures were relatively consistent with the spectrum obtained, with the latter being the most probable configuration.2 These could be interpreted in terms of a stereochemically active lone pair: If we start with an undeformed octahedron we can characterize the deformation to the equilibrium structure in terms of the site of the repulsive lone pair [] Symmetry considerations would seem to dictate that the lone pair be centered on the corner, face, or edge in the equilibrium structure. Heats of formation of xenon fluorides and the fluxionality of XeF(6) from high level electronic structure calculations. Solid state does have an effect on the hybridization.
