Abstract: Several silver nitrate and perchlorate salts with 5-aminotetrazole-based
ligands have been synthesized and characterized by elemental analysis, mass
spectrometry, IR, Raman and multinuclear NMR spectroscopy. In addition, several
of the new compounds were characterized by X-ray structure analysis. The energetic
properties of the materials were assessed by differential scanning calorimetry
(DSC) analysis in combination with standard impact and friction BAM tests. The
compounds synthesized have good thermal stabilities above 225 °C and in some
instances the high sensitivities of the materials towards impact and friction make
them fall under the category of primary explosives. Some of the compounds might
present prospective use in initiation devices for civil and military applications.
