Triazene

Not to be confused with triazine or triazane.

Triazene is an unsaturated inorganic compound having the chemical formula N₃H₃. It has one double bond and is the second-simplest member of the azene class of hydronitrogen compounds, after diimide. Triazenes are a class of organic compounds containing the functional group −N(H)−N=N−. Triazene, possibly along with its isomer triimide (HNNHNH), has been synthesized in electron-irradiated ices of ammonia and ammonia/dinitrogen and detected in the gas phase after sublimation.^[1]
