Bis(1,5-diamino-4-methyl-tetrazolium)hydrazinetetrazolate: synthesis, structure and energetic properties

Abstract

Bis(1,5-diamino-4-methyl-tetrazolium)hydrazinetetrazolate (BMDATHBT) was synthesized for the first time from 1,5-diamino-4-methyl-tetrazolium sulfate (MDATS) and hydrazino bitetrazole barium (HBTBa·5H₂O) as raw materials. The structure was characterized by elemental analysis, IR, ¹HNMR and MS. A single crystal of BMDATHBT was cultivated. Its crystalline density was 1.660 g cm⁻³. BMDATHBT has high detonation pressure and detonation velocity (P = 25.93 GPa, D = 7.839 km s⁻¹), which are higher than those of TNT. Its thermal and mechanical sensitivities are moderate. The thermal decomposition products are almost all gases. Therefore, it has potential application prospects as a gas generating agent, explosive and solid propellant.
