Preparation and characterization of 5-(5-azido- 1H-1,2,4-triazol-3-yl)tetrazol-1-ol and selected energetic salts

摘要

The novel nitrogen-rich compound 5-(5-azido-1H-1,2,4-triazol-3-y1)tetrazol-1-ol (1) has been prepared and fully characterized, including multinuclear NMR spectroscopy and single-crystal X-ray diffraction. Additionally several metal and nitrogen-rich salts, including silver (2), copper(Ⅰ) (3), potassium (4), cesium (5), copper(Ⅱ) (7), ammonium (8), hydra-zinium (9), aminoguanidinium (10), as well as the respective double-salts of 4 and 8, were prepared and also well characterized. Additionally the structures of 5, 6·3H_2O and 8 were determined by single-crystal X-ray diffraction. The sensitivities towards impact, friction and electrostatic discharge were determined according to BAM standards, revealing most of the metal salts as highly sensitive and the nitrogen-rich salts as mostly moderately sensitive to insensitive. The metal salts were further tested as primary explosives.
