Tetrazene
Chemical compound
From Wikipedia, the free encyclopedia
Tetrazene is a chemical compound with the molecular formula H2N−N=N−NH2. It is a colorless explosive material. An analogue is the organosilicon derivative (tms)2N−N=N−N(tms)2 where tms is trimethylsilyl.[1] Isomeric with tetrazene is ammonium azide.

Properties
Tetrazene has eleven isomers.[2] The most stable of these is the straight-chain 2-tetrazene (H2N−N=N−NH2), having a standard heat of formation at 301.3 kJ/mol. The eleven isomers can be arranged into three groups: straight-chain tetrazenes, four-membered cyclotetrazane, and three-membered cyclotriazanes. Each straight-chain tetrazene isomer possesses one N=N double bond and two N−N single bonds.[2] Tautomerizations do occur between the isomers. The ionic compound ammonium azide is also a constitutional isomer of tetrazene.
Organometallic derivatives
A variety of coordination complexes are known for R2N2−4 (R = methyl, benzyl).[3]
