A thermally stable nitrogen-rich energetic material—3,4,5-triamino-1-tetrazolyl-1,2,4-triazole (TATT)

Abstract

The nitrogen-rich energetic material 3,4,5-triamino-1-tetrazolyl-1,2,4-triazole (TATT) was synthesized from diaminoguanidine using a straightforward method. The assumption that a 1,2,4-triazole ring is an intermediate in the one-pot reaction is supported by the synthesis of TATT from an analogous reaction of 3,4,5-triamino-1,2,4-triazole with cyanogen azide. TATT·HNO₃ crystallizes in the monoclinic system P21/c. TATT has excellent thermal stability which resembles triaminotrinitrobenzene (TATB), but with a higher positive heat of formation and greater impact insensitivity.
