Nitrosyl refers to the diatomic species with the formula NO. Nitrosyls are molecules with the general formula RNO, where R represents an unspecified substituent. A common example is nitrosyl chloride, NOCl (although its structure is better represented ONCl).
Reduction of nitric oxide gives the hyponitrite anion, NO−:
Oxidation of NO yields the nitrosonium cation, NO+:
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°.
