To achieve a balance between detonation properties and molecular stability, series of (1,2,4-oxadiazole)-bridged pyrazole derivatives have been synthesized in this work. The compounds involved were characterized by NMR spectroscopy (1H, 13C), IR spectroscopy, differential scanning calorimetry (DSC), the structures energetic salts further confirmed X-ray single-crystal diffraction. These good thermal stability low sensitivities to impact friction, which are supported calculations very well. In particular, perchlorate 6 with highest decomposition temperature 331.7 °C has better thermostability than other reported salts. addition, their velocity (D) pressure (P) calculated using EXPLO5 be around D = 7712–8693 m s–1 P 24.0–34.2 GPa, respectively, showing potential new candidates.

In this work, a new series of monocyclic compounds based on 1,2,4-oxadiazol-5(4H)-one was synthesized. The molecular structure, thermal stability and sensitivity to external stimuli for these were characterized by X-ray diffraction analysis, NMR (1H 13C) spectroscopy, IR differential scanning calorimetry (DSC) the standard BAM method. Compound 3-((2,2,2-trinitroethyl) amino)-1,2,4-oxadiazol (3) with trinitromethyl exhibits higher decomposition temperature (Td = 143°C) than that 3-(dinitromethyl)-1,2,4-oxadiazol-5-one (4) 76°C) reported in literature. addition, compound 3 lower impact sensitivities (IS) (IS 10 J) 4, N3-(2,2,2-Trinitroethyl)-1,2,4-oxadiazole-3,5-diamine (5) RDX (4: 6 J; 5: RDX: 7.4 J). Charge distribution Hirshfeld surface calculated make further research intermolecular interaction trinitromethyl. difference is mainly due existence hydrogen bonds. These results indicate has promising application prospects as energetic material.
