Energetic dipicrate hydrazide salts were synthesized by combining picric acid (PA) as anion and carbohydrazide and oxalyldihydrazide as cations in stoichiometric amounts (2 : 1 mol ratio). The structures of 2,2′‐carbonyldi(hydrazin‐1‐ium) bispicrate ( 1 ) and 2,2′‐(1,2‐dioxoethane‐1,2‐diyl)di(hydrazin‐1‐ium) bispicrate ( 2 ) were investigated by single‐crystal X‐ray diffraction analysis, illustrate that both crystals of 1 and 2 belong to the monoclinic system (space group, C2/c). The prepared salts were thoroughly characterized using NMR, IR spectroscopy, elemental analysis, and thermogravimetric‐differential thermal analysis (TG‐DTA). The detonation velocities and pressures of salts 1 (8.02 km/s, 27.8 GPa) and 2 (8.23 km/s, 30.5 GPa) were computed by using EXPLO5 code. They exhibit high density, acceptable oxygen balance, good detonation properties and admirable thermal stability.
