· W3 O7 F1

W₃O₇F is a tungsten oxide fluoride compound belonging to the mixed-valence transition metal oxide family, combining tungsten's redox chemistry with fluorine's electronegativity to create a potentially novel functional ceramic. This is a research-phase material rather than an established industrial compound; it may be investigated for photocatalytic, electrochemical, or optoelectronic applications where the fluorine-substituted tungsten oxide lattice could enable enhanced reactivity or electronic properties compared to conventional tungsten oxide (WO₃) or its hydrates.
