Abstract: A new energetic ionic salt—triaminoguanidinium 5,5′-bistetrazole-1,1′-diolate salt is synthesized based on glyoxal and guanidine hydrochloride. The structure of triaminoguanidinium 5,5′-bistetrazole-1,1′-diolate salt is characterized by using FT-IR,1H NMR, 13C{1H} NMR spectra and elemental analyses. Its optimized structure,IR spectrum and thermodynamic parameters are obtained at the DFT-B3LYP/6-31+G**theoretical level. Its detonation properties and thermal decomposition are also predicted by the formula of Kamlet-Jacobs. The results show that the density, heat of formation, detonation velocity and detonation pressure are 1.78 g/cm3,710 kJ/mol, 9.01 km/s and 34.88 GPa,respectively.

Key words: ordnance science and technology, energetic material, detonation property, synthesis, density functional theory
