exhibit fluoride-ion donor properties in the absence of donor ligands. We report the first synthesis of donor-stabilized [MF5 ]+ derived from a transition-metal hexafluoride via fluoride-ion abstraction using WF6 (L) (L=2,2'-bipy, 1,10-phen) and SbF5 (OSO) in SO2 . The [WF5 (L)][Sb2 F11 ] salts and [WF5 (1,10-phen)][SbF6 ]⋅SO2 have been characterized by X-ray crystallography, Raman spectroscopy, and
