The salts OD3ASF6-, OD3SBF6-1 and partially deuterated OH3SBF6- were prepared and characterized by X-ray and neutron diffraction techniques, DSC measurements, and vibrational spectroscopy. At room temperature, OH3ASF6- exists in a plastic phase where ions, centered on the atomic positions of the NaCl structure, are in motion or oscillation. No valuable information on atomic distances or angles in OH3SBF6- could be obtained due to these dynamic structural disorder problems. For OH3SBF6- the phase transition from an ordered to a disordered phase was shown to occur above room temperature.
