Cu2OF2

Cu₂OF₂ is a mixed-valence copper oxide fluoride ceramic compound combining copper, oxygen, and fluorine in a single crystalline structure. This material belongs to an emerging class of anionic-mixed ceramics with potential applications in solid-state ionics, catalysis, and electronic devices where the presence of both oxide and fluoride anions may confer unique properties. Cu₂OF₂ remains largely in the research phase; its development is motivated by interest in tailoring ion conductivity, redox activity, and structural flexibility through compositional design, though industrial-scale applications are not yet established.
