Eight new energetic salts based on 1-methoxy-5-nitroiminotetrazole, which was obtained by nitration of 1-methoxy-5-aminotetrazole, were synthesized. Guanidinium (5), aminoguanidinium (6), diaminoguanidinium (7), triaminoguanidinium (8), carbohydrazidinium (9), 3-amino-1,2,4-triazolium (10), 4-amino-1,2,4-triazolium (11), and 3,5-diamino-1,2,4-triazolium (12) salts were characterized by vibrational spectroscopy (IR, Raman), multinuclear spectroscopy (H-1, C-13, N-15), elemental analysis, and single crystal X-ray diffraction analysis. Salts 5 center dot 1/3H(2)O and 7-9 crystallize in the triclinic space group P (1) over bar 1, whereas compounds 6 and 10 crystallize in the monoclinic space groups C2/c and P2(1)/n, respectively. Compound 11 is in orthorhombic group P2(1) 2(1) 2(1). In addition, the heats of formation (Delta H-f), and detonation properties (pressure and velocity) were calculated using Gaussian 03 and EXPLO5 programs, respectively. Thermal stabilities were obtained by DSC measurements and the sensitivities toward impact and friction were determined by BAM methods.
