Nitrogen oxide

Nitrogen oxide may refer to a binary compound of oxygen and nitrogen, or a mixture of such compounds:

Charge-neutral

• Nitric oxide, also known as nitrogen monoxide (NO), nitrogen(II) oxide
• Nitrogen dioxide (NO₂), nitrogen(IV) oxide
• Nitrous oxide (N₂O), nitrogen(−I,III) oxide
• Nitrosylazide (N₄O), nitrogen(−I,0,I,II) oxide
• Oxatetrazole (N₄O)
• Dinitrogen trioxide (N₂O₃), nitrogen(II,IV) oxide
• Dinitrogen tetroxide (N₂O₄), nitrogen(IV) oxide
• Dinitrogen pentoxide (N₂O₅), nitrogen(V) oxide
• Trinitramide (N(NO₂)₃ or N₄O₆), nitrogen(0,IV) oxides

Anions
