DescriptionA nitrite (NO2-) is a salt of nitrous acid (HNO2). The anion is symmetric with equal N-O bond lengths and a O-N-O bond angle of ca. 120°. On protonation the unstable weak acid nitrous acid is produced. Nitrite can be oxidised or reduced, with product somewhat dependent on the oxidizing/reducing agent. The nitrite ion is an ambidentate ligand and is known to bond to metal centres in at least five different ways.[1] Nitrite is important in biochemistry as a source of the vasodilator nitric oxide.
