With the above criteria in mind, we prepared a new oxyfluoride, Cu3Al2OF10, via precipitation and annealing of the corresponding hydrated fluorides Cu3Al2F12(H2O)12. This mixed metal cations Cu-Al oxyfluoride will add to the few cases reported in the literature such as CuWO3F2 and Ca2CuO2F2.5 prepared through either solid state chemistry or via reaction of the corresponding oxides with F2.
