Tetraazidomethane, C(N3)4, is a colorless, highly explosive liquid.

Its chemical structure consists of a carbon atom covalently bonded to four azide functional groups.

It was first prepared by Klaus Banert in 2006 by reaction of trichloroacetonitrile with sodium azide.

[1] As with other polyazides, tetraazidomethane has interest as a high-energy-density material with potential uses in explosives, propellants, or fireworks.

Banert has reported that tetraazidomethane participates in a number of reactions including hydrolysis, cycloaddition reactions with alkenes and alkynes, and reaction with phosphines to form phosphazenes.
