Structural characteristics of dicarbon polyfluoride

In chemical analysis and XRPA studies, it has been found that the products of fluorination of graphite, graphite bifluoride, and tetracarbon polyfluoride with gaseous and liquid fluorooxidants (ClF₃, ClF₅, XeF₂, and FNO₃) and their solutions in anhydrous hydrogen fluoride and freon-113 at 20–100°C, having a limiting composition, are second stage intercalated compounds based on dicarbon polyfluoride with the corresponding fluorooxidant, or the reduced form of fluorooxidant, or a fluorooxidant and a solvent. The degree of C-F bond ionicity in C₂F was higher than in CF, but lower than in C₄F. However, the bond is closer in character to the covalent C-F bond in monocarbon polyfluoride.
