Monocyclic Bis(<i>N</i>‑nitramine) Triazole: A High-Density Energetic Material with Exceptionally Weak N-N Bond.

ABSTRACT: The N-N single bond is inherently intriguing due to its high energy storage capacity, whether in polynitrogen systems or nitramine-based molecules. However, the synthesis of compounds featuring exceptionally weak N-N single bonds is often hindered by their intrinsic high reactivity and instability. Here, we report the design and synthesis of a monocyclic dual N-nitramine with an ultralow N-N bond dissociation energy: 2,4-dinitroamino-5-nitro-2,4-dihydro-3H-1,2,4-triazol-3-one (2). This compound was obtained via the nitration of the diaminonation intermediate of NTO and exhibits a remarkably high crystal density (1.969 g cm^-3 at 298 K and 2.025 g cm^-3 at 100 K), along with outstanding detonation performances (Dv = 9072 m s^- 1,
