Thermally stable energetic materials have broad applications in the deep mining, oil and natural exploration, aerospace industries. The quest for thermally (heat-resistant) with high energy output low sensitivity has fascinated many researchers worldwide. In this study, two different series of salts based on pyrazole–oxadiazole pyrazole–triazole (3–23) explosophoric groups been synthesized a simple straightforward manner. All newly compounds were fully characterized by IR, ESI-MS, multinuclear NMR spectroscopy, elemental analysis, thermogravimetric analysis–differential scanning calorimetry measurements. structures 3, 7, 22 supported single-crystal X-ray diffraction studies. density, heat formation, properties (detonation velocity detonation pressure) all range between 1.75 1.94 g cm–3, 0.73 to 2.44 kJ g–1, 7689 9139 m s–1, 23.3 31.5 GPa, respectively. are insensitive impact (>30 J) friction (>360 N). addition, 4, 6, 10, 14, 17, 21, 22, 23 show onset decomposition temperature (Td 238 397 °C) than benchmark RDX = 210 °C), HMX (279 HNS (318 °C). It is noteworthy that backbones greatly influence their physicochemical properties. Overall, study offers perspective nitrogen-rich explores relationship structure performance.

The incessant pursuit of heat-resistant explosives with balanced energetic performance and safety is indispensable in civil military sectors, particularly when employed harsh environments. Herein, a new nanostructured highly metal–organic framework (E-MOF), based on nickel(II) sodium(I) mixed-metal has been constructed using an poly tetrazole molecule by the hydrothermal approach. Na/Ni-MOF was thoroughly characterized infrared radiation (IR), thermogravimetric analysis differential scanning calorimetry, electron microscopy, powder X-ray diffraction analyses. Further, crystal structure authenticated single analysis, their packing features were well explored, revealing wave-like 3D having density 1.985 g cm–3. This mixed-metallic E-MOF demonstrated good enthalpy combustion (−7.91 kJ·g–1), velocity detonation (VOD = 7410 m s–1) exceeding that trinitrotoluene (TNT, 6820 m/s) Hexanitrostilbene (HNS, 7164 m/s), excellent insensitivity [impact sensitivity (IS) > 40 J friction (FS) 360 N]. Additionally, it exhibits outstanding thermal stability (Td 387 °C). These fine-tuned properties are superior to those continuously used benchmark HNS 2,4,6-triamino-1,3,5-trinitrobenzene, suggesting newly reported tetrazole-based beneficial for improved physical performance. results given present work highlighted advantages as potential explosive future applications.
