Nickel(II) nitrite is an inorganic compound with the chemical formula Ni(NO2)2. Anhydrous nickel nitrite was first discovered by Cyril Clifford Addison on 1961. He allowed gaseous nickel tetracarbonyl to react with dinitrogen tetroxide, yielding a green smoke. Nickel nitrite was the second transition element anhydrous nitrite discovered after silver nitrite. Nickel nitrite decomposes when heated to 220°C, however it can be heated up to 260°C in argon. The nitrite is covalently bonded to nickel, and the material is slightly volatile. The infrared spectrum of the solid has absorption bands at 1575, 1388, 1333, 1240, 1080, and 830 cm−1. Liquid dinitrogentetroxide oxidises nickel nitrite to nickel nitrate.
