the ammonia adducts of the copper and silver salts were isolated. The reaction of HTNTz with hydrazine and hydroxylamine resulted in the formation of hydrazinium 5-(dinitromethyl)tetrazolate and hydroxylammonium 5-(dinitromethyl)-1H-tetrazolate, respectively. Acid treatment of both 5-(dinitromethyl)tetrazolates resulted in the isolation of 5-(dinitromethylene)-4,5-dihydro-1H-tetrazole, which was converted

To challenge the limits of nitro groups associated with a tetrazole ring, the polynitrotetrazoles, 2,5-bis(dinitromethyl)-2H-tetrazole, and 2-(dinitromethyl)-5-(trinitromethyl)-2H-tetrazole as well as their salts, were designed, synthesized, and characterized. The neutral compounds were also studied by natural bonding orbital (NBO) and Hirshfeld surface calculations. The heats of formation were calculated

A highly energetic, high-oxygen carrier suitable as high-performing green replacement for ammonium perchlorate includes halogen-free ionic salts consisting of fuel cations and over-oxidized anions containing multiple nitro- or nitromethyl-substituted azolyl ligands. The over-oxidized anions include a central atom selected from the group consisting of boron, aluminum, or gallium. Characteristically, the carrier has sufficient amounts of oxygen for complete or near complete combustion of the over-oxidized anions, the fuel cations, metal additives and binders.

A series of energeticnitrogen-richsalts comprised of a 5-(trinitromethyl)tetrazolate anion and high-nitrogen cations was synthesized by simple and efficient chemical routes from readily available commercial reagents. These energetic materials were fully characterized by IR and multinuclear NMR (1H, 13C, 14N) spectroscopy, elemental analysis, and differential scanning calorimetry (DSC). Additionally
