An SCF-Xαstudy of the ionization energies of the octahedral complexes XF6n-(X=S, P, Si, Al)

Abstract
SCF-Xα calculations are reported for AlF6 3-, SiF6 2-, PF6 - and SF6. The results for SF6 are comparable with those obtained from a recent many-body perturbation theory calculation. Ionization energies for the complexes calculated by the transition state technique agree well with experiment.
