A highly energetic material 3,3ʹ-bis(trinitroethylamino)-4,4ʹ-bisfurazan (BTNEABF) was synthesized by cyanation, addition, ring formation, and condensation reaction. According to the results of NMR, single-crystal X-ray diffractometry and DSC, this compound has a high density (1.833 g·cm−3) and positive heat of formation (681.3 kJ·mol−1). The calculated detonation velocity (D = 9045 m·s−1), pressure (P = 37.1 GPa), and sensitivity (IS = 40 J) are better than that of RDX ((D = 8795 m·s−1, P = 34.9 GPa, IS = 7.4 J), which indicated that this material is a potential substitute for the traditional energetic materials.
