Abstract C 60(SbCl 4F) x was made by reacting C 60 and antimony tetrachloride fluoride, SbCl 4F. Infrared absorption bands in the ranges 800–950 and 950–1200 cm −1 showed that there is C–Cl and C–F coupling. When C 60(SbCl 4F) x is heated at 100°C for 12 h, C 60 is recovered with the removal of all the SbCl 4F coupling. Raman spectroscopy shows that the sample is sensitive to a laser beam intensity of 100 mW/mm 2 with decomposition to SbCl 4F and C 60. X-ray diffraction indicates that the sample is non-crystalline; it may be due to the presence of the (SbCl 3F 2) 4 tetramer which is too large to occupy the interstitial sites of C 60.
