Key result
Hydrazinium azide hydrazinate was synthesized and characterized, showing it is less hygroscopic and volatile than hydrazinium azide and produces more ammonia upon explosion.
The synthesis of hydrazinium azide hydrazinate provides a less hygroscopic and less volatile alternative to hydrazinium azide with different explosion products.
May offer a handling-improved azide energetic; leaves open scalability, safety, and performance validation before any use.
Hydrazinium azide hydrazinate, [N2H5]+[N3]−ċN2H4 was synthesized from equimolar amounts of hydrazinium azide and hydrazine and characterized by single crystal X-ray diffraction: monoclinic, P 21/c, a=6.3704(2), b=12.1111(4), c=6.9940(2) Å, β=91.8666(2) °, V=539.32(3) Å3, Z=4, ρ=1.320 g cm−1. The compound is less hygroscopic and less volatile than hydrazinium azide. Explosion of [N2H5]+[N3]−ċN2H4 yielded dinitrogen (N2), ammonia (NH3) and dihydrogen (H2). Compared to hydrazinium azide, the hydrazine adduct produces larger amounts of ammonia in the explosion.

Hammerl et al. (2001) studied this question. Hydrazinium azide hydrazinate vs. Hydrazinium azide was evaluated on Compound characterization and explosion products. Hydrazinium azide hydrazinate was synthesized and characterized, showing it is less hygroscopic and volatile than hydrazinium azide and produces more ammonia upon explosion.
