Abstract A novel chemical compound poly-dicarbon monofluoride represented by the formula (C 2 F) n and having a crystalline structure of packing form featured by its layer structure as shown in FIG. 12 hereof stacked with an interlayer spacing of about 9.0 A. Such new compound can be produced under relatively mild reaction conditions and obtained in a yield as large as 100% with respect to not only the carbon material employed but also the fluorine employed. The new compound is black under the formation conditions and of low crystallinity, but it can be easily converted to that of high crystallinity and white color by heat treatment in a fluorine atmosphere. The new compound has a wide variety of uses, for example, as lubricants, stain-resistant and water-repellent materials, cathode materials in high energy primary cells, etc.
