Nitryl chloride is a volatile inorganic compound with formula ClNO2. At standard conditions it is a gas.

Formation[]

Nitryl chloride can be formed in the reaction of dinitrogen pentoxide with chlorides or hydrogen chloride:[1][2]

N2O5 + 2HCl → 2ClNO2 + H2O
N2O5 + NaCl → ClNO2 + NaNO2

This kind of reaction can occur in the Earth's atmosphere.
