IR and Raman spectra of X+AuF6 -(X = ClF 2, CtO 2, CIOF 2, ClF4, ClF6) were studied. The vibration frequencies of these compounds in the solid phase and in solutions in anhydrous HF were assigned. Peculiar feature~ of the vibrational spectra of solid X+AuF6 -, associated both with structural translbrmations of cations and anions in the crystal lattice field and cation--anion interaetious and also with the Jahn--Teller effect, Fermi resonance, non-rigid intramoleeiular rearrangements., etc., were discussed.
