V6 O7 F5

V₆O₇F₅ is a mixed-valence vanadium oxide fluoride compound belonging to the family of transition metal oxyfluorides, which are primarily investigated as functional materials in electrochemistry and solid-state chemistry. This material is largely experimental and represents research into vanadium-based compounds for potential applications in energy storage and ionic conductivity, where the combination of oxygen and fluorine ligands can modulate electronic structure and ion transport pathways. The oxyfluoride family is notable for tunable redox chemistry and structural flexibility compared to simple oxides or fluorides alone.
