Preparation and characterization of 3,5-dinitro-1H-1,2,4-triazole

3,5-Dinitro-1H-1,2,4-triazole was isolated as an impact and friction sensitive solid, and fully characterized for the first time. The compound decomposes explosively upon heating to 170 °C. Impurities might lower the decomposition temperature and increase the sensitivity of the material.
