Nitrosyl compounds

Nitrosyl is a part of the name of chemical compounds that contain NO ⁺ or NO ^- ions, the name is more common for the former. The compounds are derived from nitrogen monoxide NO.

The reduction of nitrogen monoxide results in the hyponitrite - anion NO ^{- which is} unstable at temperatures above −95 ° C :

${\displaystyle \mathrm {NO+e^{-}\longrightarrow NO^{-}} }$

The very easy oxidation of NO produces the nitrosyl or nitrosonium cation NO ⁺ :

${\displaystyle \mathrm {NO\longrightarrow NO^{+}+e^{-}} }$

General structure of nitroso compounds

Linear and angled metal nitrosyl complexes

Examples of nitrosyl compounds are:

• Nitrosyl halides
  • Nitrosyl fluoride NOF
  • Nitrosyl chloride NOCl
  • Nitrosyl bromide NOBr
• Other
  • Black Roussin ammonium salt NH ₄ [Fe ₄ S ₃ (NO) ₇ ]
  • Nitrosyl sulfuric acid / nitrosyl hydrogen sulfate NOHSO ₄
  • Nitrosyl tetrafluoroborate [NO] BF ₄
  • Nitrosyl cyanide NOCN
  • Nitrosyl azide NON ₃
  • Nitrosyl perchlorate NOClO ₄
  • Nitrosyltricarbonyltriphenylphosphine manganese (-I) [Mn (CO) ₃ (NO) P (C ₆ H ₅ ) ₃ ]
  • Nitrosyl-tris (triphenylphosphane) -rhodium [(C ₆ H ₅ ) ₃ P] ₃ Rh (NO)
  • Nitrosyl hexafluorophosphate NOPF ₆
  • Nitrosobenzene C ₆ H ₅ NO

Nitrosyl salts react with water to form nitrous acid

Organic compounds of the general form R ¹ R ² R ³ C-N = O, which are formally derived from the NO ^- ion, are referred to as nitroso compounds . The common feature of these compounds is the NO group, which is known as the nitroso group as a functional group .

If NO (i.e. nitrogen monoxide) occurs neutrally or as an anion or cation as a ligand in complex compounds , these are sometimes referred to as metal-nitrosyl complexes. The nitrosyl ion is isoelectronic to CO, N ₂ or CN ^- , has a degree of bond of 3 and occurs as a nitrosyl radical in mononuclear complexes in a linear or angled arrangement.
