What is "triazane"

n. (context chemistry English) the nitrogen compound NH₂NHNH₂, or any of its hydrocarbyl derivatives

Triazane (also systematically named 1,1,2,3,3-pentahydrido-1,2,3-triazy-[3]catena), or aminohydrazine is an inorganic compound with the chemical formula (also written or ). Triazane is the third simplest acyclic azane (the simplest are ammonia and hydrazine). It can be synthesised 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. Triazane was first synthesised as a ligand of the silver complex ion: tris(μ-triazane-κN,N)disilver(2+).
