We describe an effective scheme for the synthesis of a new energetic compound – 3-azido-4-(2H-tetrazol-5-yl)furazan from 4-amino-N'hydroxyfurazan-3-carboximidamide. The structure of 3-azido-4-(2H-tetrazol-5-yl)furazan was proved by 1Н and 13С NMR spectroscopy, mass spectrometry, and X-ray structural analysis. 3-Azido-4-(2H-tetrazol-5-yl)furazan crystallized in monoclinic syngony, space group Р21/n, monocrystal density d 1.953 g·cm–3 (100 K). According to differential scanning calorimetry data, 3-azido-4-(2H-tetrazol-5-yl)furazan melts at 103.3°С, while the maximum of thermal decomposition exotherm was observed at 185.6°С. The sensitivity of 3azido-4-(2H-tetrazol-5-yl)furazan to impact (2 kg, 25 cm, 36% explosion frequency) and to friction (1450 kg·cm–3 lower limit) was at the level of pentaerythritol tetranitrate. The salts of 3-azido-4-(2H-tetrazol-5-yl)furazan with ammonia and guanylurea were also obtained and characterized.
