Niobium(V) oxynitrate is an inorganic compound with the proposed formula NbO(NO3)3. A single publication claims that niobium(V) oxynitrate is produced by the reaction of niobium pentachloride and dinitrogen pentoxide at 30 °C:[1]

- NbCl5 + 4N2O5 → NbO(NO3)3 + 5NO2Cl
Nitryl chloride is produced as a byproduct.
Attempts failed to produce niobium(V) oxynitrate by the reaction dinitrogen tetroxide and niobium pentachloride in acetonitrile in the formation of the acetonitrile niobium dioxide nitrate complex.[2]
