Triazane is an inorganic compound with the chemical formula NH₂NHNH₂ or N₃H₅.^[2] Triazane is the third simplest acyclic azane after ammonia and hydrazine. It can be synthesized from hydrazine but is unstable and cannot be isolated in the free base form, only as salt forms such as triazanium sulfate. Attempts to convert triazanium salts to the free base release only diazene and ammonia.^[3] Triazane was first synthesized as a ligand of the silver complex ion: tris(μ²-triazane-κ²N¹,N³)disilver(2 ).^{[clarification needed]} Triazane has also been synthesized in electron-irradiated ammonia ices and detected as a stable gas-phase product after sublimation.^[4]

Compounds containing the triazane skeleton

Several compounds containing the triazane skeleton are known, including 1-methyl-1-nitrosohydrazine (NH₂−N(CH₃)−N=O), produced from the solventless reaction of methylhydrazine (CH₃NHNH₂) and an alkyl nitrite (R−O−N=O):

CH₃NHNH₂ RONO → NH₂N(CH₃)NO ROH

1-Methyl-1-nitrosohydrazine is a colorless solid, sensitive to impact, but not to friction. It melts at 45 °C and decomposes at 121 °C.
