Nitrite is an ambidentate ligand and can form a wide variety of coordination complexes by binding to metal ions in several ways. [2] Two examples are the red nitrito complex [Co(NH 3) 5 (ONO)] 2+ is metastable, isomerizing to the yellow nitro complex [Co(NH 3) 5 (NO 2)] 2+. Nitrite is processed by several enzymes, all of which utilize ...
Nucleophilic substitution reactions between halocarbons [5] or organosulfates [6] with silver or alkali nitrite salts. Nitromethane can be produced in the laboratory by treating sodium chloroacetate with sodium nitrite. [7] Oxidation of oximes [8] or primary amines. [9] Reduction of β-nitro alcohols [10] or nitroalkenes. [11]
The difference between the resulting molecular structures of nitro compounds and nitrates (NO − 3) is that the nitrogen atom in nitro compounds is directly bonded to a non-oxygen atom (typically carbon or another nitrogen atom), whereas in nitrate esters (also called organic nitrates), the nitrogen is bonded to an oxygen atom that in turn ...
These two forms are sometimes called nitro and nitrito. These isomers can be interconverted in some complexes. [4] An example of chelating nitrite is [Cu(bipy) 2 (O 2 N)]NO 3 – "bipy" is the bidentate ligand 2,2′-bipyridyl. This bonding mode is sometimes described as κ 2O,O-NO 2.
Nitrite is also a common ligand that can coordinate in five ways. The most common are nitro (bonded from the nitrogen) and nitrito (bonded from an oxygen). Nitro-nitrito isomerism is common, where the nitrito form is usually less stable. [70] Fuming nitric acid contaminated with yellow nitrogen dioxide
Nitrogen cycle. Nitrification is the biological oxidation of ammonia to nitrate via the intermediary nitrite.Nitrification is an important step in the nitrogen cycle in soil.The process of complete nitrification may occur through separate organisms [1] or entirely within one organism, as in comammox bacteria.

Nitrosation is typically performed with nitrous acid, formed from acidification of a sodium nitrite solution. Nitrous acid is unstable, and high yields require a rapid reaction rate. NO + synthon transfer is catalyzed by a strong nucleophile, such as (in order of increasing efficacy) chloride, bromide, thiocyanate, or thiourea.
