We have examined graphite salts of the composition C23nSbF6(CH3NO2)1,7 n = 1,2 by121Sb Mössbauer spectroscopy at 4.2K. The spectra reveal a strong and narrow feature in the Sb5+ region and no evidence of any features in the Sb3+ region. This result is in general accord with the expectation of only Sb5+ in the chemical form of SbF6− anion in the intercalate layers.
