The structure of the solid adducts of SF4 with several fluoride acceptors has been studied by investigations of the 18F exchange between S18F4 and BF3 and between SF4 and B18F4, the infrared spectrum of SF4.BF3, and the Raman spectra of SF4.BF3, SF4.PF5, SF4.AsF5, and SF4.SbF5. The experimental observations are best accounted for in terms of an ionic structure SF3+.MXn− in each case, but there is good evidence for relatively strong fluorine bridging between the ions.In anhydrous hydrogen fluoride solution, SF4 and the adducts SF4.BF3 and SF4.SbF5 were studied conductimetrically and by 19F nuclear magnetic resonance. Both methods indicate complete ionization of the adducts to SF3+ and the complex fluoroanion. SF4 is a weak base in hydrogen fluoride ionizing to SF3+ and HF2−.
