Fe6 O10 F2

Fe₆O₁₀F₂ is an iron oxide fluoride compound belonging to the mixed-valence iron oxide family, combining ferric and ferrous iron states with fluoride incorporation. This material is primarily investigated in research contexts for electrochemical energy storage and magnetic applications, where the fluoride substitution modulates electronic structure and ion transport compared to conventional iron oxides. Its mixed oxidation state and anionic doping make it a candidate for next-generation battery cathodes and magnetoelectric devices, though it remains largely experimental rather than in widespread industrial production.
