Caution explosive! Homoleptic azides are of great interest as polynitrogen compounds particularly because of their high energy content. A recent breakthrough is the first synthesis and characterization of the highly sensitive neutral tellurium azide [Te(N3)4] and of ionic (N5)+[P(N3)6] containing 23 nitrogen atoms.
