Chromium azide is an inorganic chemical compound with the formula Cr(N3)3.

Properties

Chromium azide formation has been investigated from chromium salts and sodium azide. It was separated in 1922 through the evaporation of a dry crystalline chromium(III) nitrate solution in absolute alcohol with sodium azide.[1] Through a spectrophotometric study, it was shown that the chromium(III) nitrate solution's green color was due to the mono-azido-chromium(III) complex. Two absorbency maxima were located at 445 and 605 nm.[1] Chromium azide has luminescence properties from its optically active Cr3+ ions.[2]
