There is an urgent demand for novel energetic materials with improved performance to serve as oxygen suppliers (oxidizers) and high-energy additives. Synthesis and characterization of compound that combines both of the above roles, bis-(2-difluoroamino-2,2-dinitroethyl)nitramine (1), is reported. 1 was synthesized by difluoroamination of bis(2,2-dinitroethyl)nitramine in good yield. The analysis of X-ray diffraction data shows that NF2-groups has a significant contribution into a very high density of 1, 2.032 g cm−3 at 298 K. The positive oxygen balance (+8%) makes it an attractive oxidizer, the rocket specific impulse is improved to 277 s vs 265 s for standard ammonium perchlorate-based formulation. Furthermore, the detonation performance of 1 reaches the level of most powerful explosive, CL-20. As a way to tune the melt-casting temperature and decrease the high friction sensitivity of 1, its eutectics with trinitrotoluene were proposed.
