For the first time,
the highly sensitive 1-(nitratomethyl)-5H-tetrazole
(1-NAMT) was synthesized, representing the shortest
possible 1-(nitratoalkyl)-5H-tetrazole with a combined
nitrogen and oxygen content of 81.4%. Compared to its related ethyl
derivative, 1-(nitratoethyl)-5H-tetrazole, it exhibits
improved oxygen balance, resulting in higher detonation parameters.
1-NAMT was thoroughly analyzed by single-crystal diffraction experiments
accompanied by elemental analysis, IR spectroscopy, and multinuclear
(1H, 13C, and 14N) NMR measurements.
The thermal behavior of 1-NAMT was analyzed by differential thermal
analysis supported by thermogravimetric analysis. Furthermore, energetic
coordination compounds (ECCs) of Cu with different inorganic (e.g., nitrate, chlorate, and perchlorate) and nitroaromatic
anions (e.g., picrate and styphnate) were synthesized
and thoroughly analyzed. It is shown that the formation of ECCs with
nitroaromatic anions (T
dec ∼ 180
°C) is a suitable strategy to improve the rather low thermal
stability of 1-NAMT (125 °C).
