Graphite intercalation compound of magnesium fluoride and fluorine

Abstract A graphite intercalation compound of C x F(MgF 2 ) y was prepared under a fluorine atmosphere of 1 atm at temperatures of 20–350°C. The 1st stage compound has the identity period of 9.3–9.4A. ESCA and 19 F NMR spectra indicate that the chemical interaction of intercalated fluorine with carbon is similar to that for graphite fluoride, however, with C x F(MgF 2 ) y having slightly mobile fluorine atoms chemically adsorbed on carbon atoms of graphite layers.
