Cu6 O1 F11

Cu₆OF₁₁ is an experimental mixed-valence copper oxide fluoride compound belonging to the class of layered metal halide semiconductors. This material is primarily of research interest in solid-state chemistry and materials science, where it is being investigated for its potential electronic and optical properties arising from its unusual copper coordination environment and mixed-anion framework. Its development represents early-stage exploration within the broader family of copper-based semiconductors and halide perovskite derivatives, with potential applications emerging in emerging electronic and photonic devices, though industrial deployment remains limited.
