Syntheses of salts with 4,6‐bis(nitroimino)‐1,3,5‐triazinan‐2‐one (DNAM), 3,5‐dinitro‐1,2,4‐cyclopentanetrione (DDCP), 3‐nitroiminotriazolate, and 5‐nitroiminotetrazolate as anions yielded moderately dense nitro‐containing energetic salts that are thermally stable to >200 °C (measured by thermogravimetric analysis). Di(aminoguanidine) 5‐nitroiminotetrazolate ( 8 ) crystallizes in the monoclinic space group P 2(1)/ c with an essentially planar 5‐nitroiminotetrazolate dianion. Based on experimental and calculated densities, and theoretical calculations carried out by using the Gaussian 03 suite of programs, all of the salts have calculated detonation pressures and velocities that exceed those of 2,4,6‐trinitrotoluene (TNT) and a few have values that approach those of triaminotrinitrobenzene (TATB).
