The thermal decomposition of six related nitraminotctrazoles and nitramino‐1, 2, 4‐triazoles at slow (5°C/min, DSC) and fast (⪈ 70°C/s, FTIR/temperature profiling) heating rates is described. The nitramine protion of the molecule appears to initiate the degradation in all cases except 5‐nitraminotetrazole (5‐NATZ) where the tetrazole ring is the trigger linkage. The crystal structures of DNTP and 5‐NATZ are described and help explain the decomposition process. DNTP contains one of the longest N‐NO 2 bonds known for a nitramine (1.49 Å). 5‐NATZ was found to be a nitrimine rather than a nitramine.
