A ladder‐like 1D energetic metal‐organic framework, sodium 6‐nitro‐5‐oxidopyrazolo[3,4‐c][1,2,5]oxadiazol‐4‐ide was first synthesized from the potassium salt. The sodium salt with an interesting furazan‐pyrazole system which is first synthesized by an intramolecular condensation, is fully characterized by crystal X‐ray diffraction, elemental analysis, IR spectroscopy. The sodium salt shows a density of 1.88 g cm −3 , a high decomposition temperature of 258 o C, and a promising calculated detonation velocity of 7760 m s −1 . It has an impact sensitivity of 16 J which makes it a replacement as a thermally stable energetic material. Besides, the natural compound 6‐nitro‐4H‐pyrazolo[3,4‐c][1,2,5]oxadiazole 5‐oxide shows the best energetic properties with calculated detonation velocity of 9407 m s −1 and calculated detonation pressure of 40.4 GPa.
