Iodine nitrate is a chemical with formula INO₃. (It differs from iodine nitrite with formula INO₂.)[1]

Preparation

The compound was first produced by the reaction of mercury(II) nitrate and iodine in ether.[1]

Iodine nitrate is also prepared by the reaction of silver nitrate and iodine within an acetonitrile, ether, or methanol solution.[1]

As a gas it is slightly unstable, decaying with a rate constant of -3.2×10⁻² s⁻¹.[2] Iodine nitrate has been studied for its potential to actually form in the atmosphere and help to destroy ozone. Relevant reactions are IONO₂ → IO + NO₂ or IONO₂ → I + NO₃ and I + O₃ → IO + O₂.[3]
