4,4'-(Triaz-1-ene-1,3-diyl)bis(1,2,5-oxadiazol-3-amine) was designed and synthesized with 3,4-diaminofurazan and triazene bridges, which was fully characterized by NMR, IR, elemental analyses, and single crystal X-ray diffraction. The results of structural and physicochemical characterization of 4,4'-(triaz-1-ene-1,3-diyl)bis(1,2,5-oxadiazol-3-amine) showed that this compound exhibits particularly high formation heats (ΔHf=926.32 kJ mol-1) which is higher than that of all currently reported furazan-based energetic compounds, excellent detonation performance (D=8151 m s-1, P=28.55 GPa). In addition, this compound is insensitive to external mechanical stimuli (IS=40 J FS=289 N). Its crystal packing, intermolecular interaction and ESP play an important role in reducing sensitivity. Further, its thermal decomposition temperature is 172.6 °C. This work provides the inspiration for designing nitrogen rich energetic compounds, especially triazene bridges.
