Niobium(V) oxynitrateis aninorganic compoundwith the proposed formula NbO(NO₃)₃.A single publication claims that niobium(V) oxynitrate is produced by the reaction ofniobium pentachlorideanddinitrogen pentoxideat 30 °C:^[1]

NbCl₅+ 4N₂O₅→ NbO(NO₃)₃+ 5NO₂Cl

Nitryl chlorideis produced as a byproduct.

Attempts failed to produce niobium(V) oxynitrate by the reactiondinitrogen tetroxideand niobium pentachloride inacetonitrilein the formation of the acetonitrile niobium dioxide nitrate complex.^[2]
