Abstract
- 4,4′-Azo-bis(1,2,4-triazolone) (ZTO) based salts from alkaline (Li<superscript>+</superscript>, K<superscript>+</superscript>, Na<superscript>+</superscript>, and Cs<superscript>+</superscript>), alkaline earth metal salts (Mg<superscript>2+</superscript>, Ca<superscript>2+</superscript>, Sr<superscript>2+</superscript>, and Ba<superscript>2+</superscript>) 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<superscript>+</superscript>, K<superscript>+</superscript>, Cs<superscript>+</superscript>, Mg<superscript>2+</superscript>, Ca<superscript>2+</superscript>, Sr<superscript>2+</superscript>, Ba<superscript>2+</superscript>, and N<subscript>2</subscript>H<subscript>5</subscript><superscript>+</superscript>) 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<subscript>50</subscript> > 60 cm). In particular, the barium, caesium and strontium salts are of great interest as potential high-density insensitive materials. [ABSTRACT FROM AUTHOR]
