· Cr4 O1 F11

Cr₄O₁F₁₁ is a mixed-valence chromium oxide fluoride compound belonging to the family of metal oxyfluorides, which are ceramic materials combining ionic oxide and fluoride anions. This material is primarily of research and development interest rather than established in high-volume manufacturing; oxyfluorides are investigated for their potential in solid-state chemistry applications including ionic conductivity, catalysis, and optical properties. The fluoride component can modify electronic structure and chemical reactivity compared to simple oxides, making this composition notable for fundamental materials science exploring how anion mixing affects chromium coordination and phase stability.
