The insensitive compound bis(nitrofurazano)furazan (BNFF) with high energy-density was synthesized by three-step reactions and fully characterized. The key reduction reaction was discussed. BNFF has a high crystal density (1.839 gcm(-3)) and a low melting point (82.6 degrees C). BNFF is insensitive to impact and friction and has similar detonation velocity (8680 ms(-1)) and detonation pressure (36.1 GPa) compared to RDX.
