Abstract: The interaction of graphite with a gaseous mixture of BrF3 and Br2 at room temperature produced fluorinated graphite intercalation compounds with bromine. By changing the concentration of BrF3 in Br2 from 6.2 to 2.9 % we were able to obtain matrices of fluorinated graphene layers (C2Fx)n with x = 0.76, 0.66, 0.35, 0.25. It was shown that bromine was completely replaced by acetonitrile in the (C2Fx)n with x > 0.6, while two types of guests (CH3CN and Br2) were present between the layers with the lower fluorine loading. The Van der Waals forces hold CH3CN molecules in the (C2Fx)n host. The interaction of Br2 molecules with sp2-carbon regions remained in the C2Fx layers has donor-acceptor type. The models of guest molecules packing in host matrices (C2Fx)n are considered using the data on the stoichiometry and X-ray diffraction analysis.
