- Nitrosyl
Nitrosyl refers to the
diatomic species with the formula NO. Nitrosyls are molecules with the general formula RNO, where R represents an unspecifiedsubstituent . A common example isnitrosyl chloride , NOCl (although its structure is better represented ONCl).Nitrosyl also refers to the discrete molecule
nitric oxide , NO. Nitric oxide is a stable radical, having an unpaired electron.Reduction of nitric oxide gives the
hyponitrite anion , NO−::NO + e− → NO−
Oxidation of NO yields the
nitrosonium cation , NO+::NO → NO+ + e−
Nitrosyl as a ligand
Nitric oxide can serve as a
ligand in complexes. The resulting complexes are called metal nitrosyls, and can bond to a metal atom in two distinct modes: as NO+ and as NO−. NO+ coordinates linearly, the M−N−O angle being 180°, whereas NO− forms a bent geometry, with an M−N−O angle of approximately 120°.Nitroso compounds
Nitroso compounds are a class of
organic compound s containing the nitrosofunctional group , R−N=O.
