Energetic Complexes of 5‐(4‐Amino‐1,2,4‐triazol‐3‐on‐5‐yl)­tetrazole and Ionic Derivatives of its 2N‐Oxide

Abstract

Abstract5‐(4‐Amino‐1,2,4‐triazol‐3‐on‐5‐yl)tetrazole (HATT) was used as a ligand for the two complexes [Cu(ATT)2(H2O)2]·2H2O (5) and [Co(HATT)2(H2O)2](ClO4)3·4H2O (6). Both were characterized by X‐ray diffraction, elemental analysis and IR spectroscopy. Following the recent trend in energetic materials research of synthesis of heterocyclic 2N‐oxides the corresponding 5‐(4‐amino‐1,2,4‐triazol‐3‐on‐5‐yl)tetrazole‐2‐oxide (HATT2O) was synthesized for the first time. Two ionic energetic derivatives (ammonium, hydroxylammonium) were prepared and an intensive characterization of their energetic properties and sensitivities is given. In addition heats of formation were computed and several detonation parameters calculated using the EXPLO5 6.01 computer code.
