Stage 2 samples of graphite-SbF5 intercalVtion compounds were prepared by reacting SbF5 with HOPG at 200°C for 5 days. 121Sb Mössbauer spectra taken at 4.2K reveal an intense and narrow feature in the Sb(5+) region and a weak and broad feature in the Sb(3+) region. Interpretation of these data in terms of possible Sb(5+) and Sb(3+) intercalant species is discussed in connection with chemical aspects of intercalation.
