Nitrosyl 2671215 220461228 2008-06-19T23:43:00Z Thijs!bot 1392310 robot Adding: [[de:Nitrosyl]] [[Image:Nitroso-compound-2D.png|thumb|right|120px|General structure of nitrosyls]] '''Nitrosyl''' refers to the [[diatomic]] species with the formula [[nitrogen|N]][[oxygen|O]]. 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). Nitrosyl also refers to the discrete molecule [[nitric oxide]], NO. Nitric oxide is a stable [[Radical (chemistry)|radical]], having an unpaired electron. Reduction of nitric oxide gives the [[hyponitrite]] [[anion]], NO<sup>−</sup>: :NO + e<sup>−</sup> → NO<sup>−</sup> Oxidation of NO yields the [[nitrosonium]] [[cation]], NO<sup>+</sup>: :NO → NO<sup>+</sup> + e<sup>−</sup> ==Nitrosyl as a ligand== [[Image:Metal-nitrosyl-coordination-modes-2D.png|thumb|right|100px|Linear and bent metal nitrosyls]] {{Main|Metal nitrosyl}} Nitric oxide can serve as a [[ligand]] in [[complex (chemistry)|complexes]]. The resulting complexes are called metal nitrosyls, and can bond to a metal atom in two distinct modes: as NO<sup>+</sup> and as NO<sup>−</sup>. NO<sup>+</sup> coordinates linearly, the M−N−O angle being 180°, whereas NO<sup>−</sup> forms a bent geometry, with an M−N−O angle of approximately 120°. ==Nitroso compounds== {{Main|Nitroso compound}} Nitroso compounds are a class of [[organic compound]]s containing the nitroso [[functional group]], R−N=O.
