Computational studies on two novel energetic nitrogen-rich compounds based on tetrazolone

Two novel energetic nitrogen-rich compounds 1,4-diaminotetrazol-5-one (DATO) and 1,4-dinitrotetrazol-5-one (DNTO) were proposed first and studied by quantum chemistry method with B3LYP/6-31G∗ level of theory. The optimized geometry, IR predicted spectrum and thermochemical parameters, frontier molecular orbitals and molecular electrostatic potential were calculated for inspecting the electronic structure, molecular stability and chemical reactivity. The important macroscopic properties including density, enthalpy of formation, detonation parameters and impact sensitivity have been predicted as well. As a result, two designed compounds DATO and DNTO possess positive enthalpy of formation (395.79 and 342.77 kJ/mol), impressive detonation parameters (D = 8.80 km/s, P = 33.69 GPa; D = 8.89 km/s, P = 34.98 GPa) superior to the remarkable explosive RDX, acceptable sensitivities and might be promising candidates of energetic materials.
