4,4'-Azo-bis(1,2,4-triazolone) (ZTO) based salts from alkaline (Li+, K+, Na+, and Cs+), alkaline earth metal salts (Mg2+, Ca2+, Sr2+, and Ba2+) and hydrazinium salt were synthesized in a simple, straightforward manner and were characterized by IR and NMR spectroscopy, elemental analysis. The single-crystal X-ray diffraction of seven salts (Na+, K+, Cs+, Mg2+, Ca2+, Sr2+, Ba2+, and N2H5+) are also reported. The X-ray structures show that in the title compounds, the metal atoms are bonded to the nitrogen and oxygen atoms in the bistetrazole ring to form a sandwich structure. In addition, the thermal stabilities of all the title compounds were determined using thermogravimetric-differential thermal analysis (TG-DTA). All these new materials exhibit excellent thermal stability, high density, acceptable detonation properties, and excellent insensitivity to impact (h(50) > 60 cm). In particular, the barium, caesium and strontium salts are of great interest as potential high-density insensitive materials.
