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]
