摘要：

The azido-tetrazolo tautomerizations of 3,6-diazido-1,2,4,5-tetrazine (DIAT) in different solvents were investigated with HPLC and C-13 NMR spectroscopy. 6-Amino-tetrazolo[1,5-b]-1,2,4,5-tetrazine (ATTZ) was irreversibly formed as the final product by azido-cyclization following N-2 elimination from one of the azido substituents at room temperature in DMSO. The structure of ATTZ was characterized by X-ray crystallography; differential scanning calorimetry (DSC), mass spectrometry, as well as IR and H-1 NMR and C-13 NMR spectroscopy. The crystal density was found to be 1.272 g cm(-3). DSC result suggested that ATTZ with the melting point of 84 degrees C strongly decomposes with explosion at 198 degrees C, which can be regarded as a primary explosive.
