Trinitrotriazine

Trinitrotriazine, or 2,4,6-trinitro-1,3,5-triazine, is a theoretical explosive compound. Synthesis of this compound has been elusive despite its simple structure, as conventional nitration of triazine becomes increasingly more difficult as more nitro groups are added. A successful route would more likely proceed by trimerisation of nitryl cyanide. The precursor, nitryl cyanide, was first synthesized by Christe et al in 2014, but the trimerisation was not successful.

It has a perfect oxygen balance, potentially making it a very powerful explosive, though calculations predict it would be fairly unstable and inferior to the related compound 3,6-dinitro-1,2,4,5-tetrazine.
