Fused nitrogen heterocycles emerged recently as promising scaffolds for the design of small-molecule energetic materials. Herein, we present the synthetic route to a series of new furazano[3,4-e][1,2,4]triazolo[4,3-a]pyrazines demonstrating outstanding thermal stability (the decomposition onset above 300 °C) and low mechanical sensitivity. Moreover, a favorable combination of high crystal densities (1.68–1.84 g cm–3) and high enthalpies of formation (240–960 kJ mol–1) results in decent detonation parameters of the synthesized compounds (7.1–8.5 km s–1) unveiling new prospects in smart materials design.
