In the present work we describe synthesis and properties of 1,4-diformyl-2,3,5,6-tetranitratopiperazine. The 1,4-diformyl-213,516-tetranitratopiperazine turned out to be a powerful highly energetic compound. Its physical and chemical properties were investigated by theoretical as well as experimental methods. The detonation energy of 1,4-diformyl-2,3,5,6-tetranitratopiperazine was determined to 5376 kJ/kg or 93% compared to HMX. Molecular and crystal structure of 1,4-diformyl-2,3,5,6-tetranitratopiperazine was elucidated by single crystal X-ray diffraction analysis. An interesting feature of the title substance, its rotamer equilibrium, was investigated by 2D NMR methods.
