Nickel azide is an inorganic chemical compound with the formula Ni(N3)2. It can be formed through the reaction between nickel tetracarbonyl and iodine azide.[1]

2Ni(CO)4 + 2IN3 → Ni(N3)2 + NiI2 + 8CO


Nickel azide water solution has high absorbance in the ultraviolet with a peak at 292 nm. The solution also contains hexaaquanickel cations with visible light absorption peaks at 394, 656, and 720 nm.[2] A related mixed anion compound with nicotinic acid and nicotinate exhibits EO bridging coordination (μ-1,1) on the azide, and possesses an unusual angle between the nickel and nitrogen present within the complex.[3] Like most azides, it is explosive.
