• To establish a new synthetic pathway for a key energetic salt.

Main Methods:

• Single-crystal X-ray diffraction for structural confirmation of DNAF.
• Synthesis and full characterization of nitrogen-rich salts (3-10).
• Development of an alternative nitration route for dihydrazinium 3,4-dinitraminofurazanate (5).

Main Results:

• Dihydrazinium 3,4-dinitraminofurazanate (5) demonstrated exceptional detonation performance (νD = 9849 m s(-1); P = 40.9 GPa).
• Compound 5 is identified as one of the most powerful explosives currently known.
• An effective alternative synthetic route was successfully developed, avoiding traditional acid-base reactions.

Conclusions:

• The synthesized nitrogen-rich salts, particularly compound 5, offer enhanced stability and superior explosive properties.
