Conclusion
The results obtained in the present work show that the use of the method proposed in [3] to study the structure of intercalated compounds of graphite fluoride has made it possible to resolve in principle the question of the distribution of the C2FX layers along the z axis in these compounds and to determine the nature of the arrangement of the inserted molecules between the layers.
In intercalated compounds of stage I with an “expanded structure” of the filled layer, the molecules of the inserted solvent are distributed chiefly in two layers between the C2Fx layers, whereas in the compounds with the “simple structure” they are distributed in one layer.
In the intercalated compounds of stage II, the thickness of the unfilled layer is 6 Å, and the thickness of the filled layer coincides with the thickness of the layer in the corresponding inercalated compounds of stage I with the “simple structure” of the filled layer.
The fluorine atoms in C2Fx are arranged symmetrically on each side of the carbon layer.
In the intercalated compounds heated to a temperature of ≈200°C, the graphite fluoride layers form stacks with a distance of 6.0 Å between the layers.
On the basis of the results obtained, it has been suggested that the most probable reason for the strong retention of the inserted component in the intercalated compounds of stage II is the paired linking of the edge sections of the C2Fx layers.
