ABSTRACT 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).
