Nitrosyl iodide is a chemical compound with the formula INO.[1] Alongside nitryl iodide (INO2), iodine nitrite (IONO), and iodine nitrate (IONO2), it is a member of the INOx (iodine nitrogen oxide) series of compounds, important intermediates and reservoir species in the atmospheric chemistry of iodine.[2][3][4]
Synthesis
Nitrosyl iodide is formed in a reaction of nitric oxide with iodine:[5]
- 2NO + I2 → 2NOI
Other methods are also known.
Physical properties
The compound is soluble in organic solvents. It reacts with water.
The compound is unstable and quickly decomposes:[6]
- 2NOI → 2NO + I2
Nitrosyl iodide is believed to impact tropospheric ozone levels.[3]
