The compound was characterized by single-crystal X-ray diffraction, IR spectroscopy, Raman spectroscopy, multinuclear NMR spectroscopy, elemental analysis, and differential scanning calorimetry(DSC). With the calculated(CBS-4M) heat of formation(617.0 kJ/mol) and the room temperature X-ray density(2.11 g/cm^3), impressive values for the detonation parameters such as detonation velocity(8367 m/s) and pressure(31.5 GPa) were computed using the EXPLO5 program. The superior calculated energetic performance show it could serve as a green replacement for the widely used primary explosive,lead(II) azide, which contains toxic ingredient.展开更多
