Synthesis and characterization of the energetic 5,7-diamino-2-nitro-1,2,4-triazolo[1,5-a]-1,3,5-triazine

The energetic compound 5,7-diamino-2-nitro-1,2,4-triazolo[1,5-a]-1,3,5-triazine (ANTT) was synthesized through the selective nitration of 2,5,7-triamine-1,2,4-triazolo[1,5-a]-1,3,5-triazine (TTT). This facile synthetic strategy yields a highly insensitive energetic nitrogen bicycle with potential for further functionalization. ANTT was chemically characterized by NMR, IR, and single crystal X-Ray crystallography. Its energetic sensitivities (impact, friction) were experimentally determined, and its energetic performances were calculated for the first time. This paper details the synthesis and energetic characterization of 5,7-Diamine-2-nitro-1,2,4-triazolo[1,5-a]-1,3,5-triazine.image
