Abstract: The interaction of graphite with a gaseous mixture of BrF3 and Br-2 at room temperature produced fluorinated graphite intercalation compounds with bromine. By changing the concentration of BrF3 in Br-2 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 Br-2) 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 Br-2 molecules with sp(2)-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.
