Tetrazene

Tetrazene is a chemical compound with the molecular formula H₂NN=NNH₂. It is a colorless explosive material. An analogue is the organosilicon derivative (tms)₂NN=NN(tms)₂ where tms is trimethylsilyl.<ref>Template:Greenwood&Earnshaw2nd</ref> Isomeric with tetrazine is ammonium azide.

Tetrazene explosive, commonly known simply as tetrazene, is used for sensitization of priming compositions.

Properties

Tetrazene has eleven isomers.<ref name=Li>Template:Cite journal</ref> 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.<ref name=Li/> Tautomerizations do occur between the isomers. The ionic compound ammonium azide is also a constitutional isomer of tetrazene.
