· K2 Fe2 F8

K2Fe2F8 is an inorganic fluoride compound belonging to the family of mixed-metal fluorides, which are ionic solids composed of potassium, iron, and fluorine. This material is primarily of research interest in solid-state chemistry and materials science, where it is investigated for potential applications in battery electrolytes, ionic conductors, and fluoride-based solid-state systems; it represents an experimental compound rather than an established commercial material, and engineers would encounter it in advanced energy storage research or specialized electronic applications requiring high ionic conductivity or thermal stability.
