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
