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

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 center dot 5H(2)O) as raw materials. The structure was characterized by elemental analysis, IR, (HNMR)-H-1 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.
