C-Cl and C-F coupling in C_(60)(SbCl_4F)_x

摘要

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 deg 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).
