Three stationary points of symmetry C3v, C2v, and Oh on the potential energy surface of XeF6 have been located and characterized at the self-consistent field level of theory with a large basis set. At this level of theory, and contrary to results given earlier in the literature, two of these stationary points (C2v, and O h) are determined to be transition states, with harmonic vibrational frequencies leading to the third stationary point (C3v). In addition, second-order Møller-Plesset perturbation theory, configuration interaction, and coupled-cluster energies have been determined at each of these optimized geometries. The C3v, structure is predicted to lie lowest, followed by the C2v and then the Oh structure.
