摘要：

A novel energetic salt of diaminoglyoxinium 1H, 1'H-5, 5'-bitetrazole-1, 1'-diolate (DAGBTO) was synthesized by using diaminoglyoxime (DAG) and 1H, 1'H-5, 5'-bitetrazole-1, 1'-diol (BTO) as raw materials, and its structure was characterized by elemental analysis, Fourier transform infrared spectroscopy (FT-IR) spectroscopy, 1H NMR, 13C NMR and mass spectrometry. The single crystal of DAGBTO was obtained and its structure was determined by X-ray single-crystal diffractometer. Results show that DAGBTO belongs to monoclinic space group C2/c with a density of 1.782 g·cm-3, and the cell parameters are as follows: a=11.3121 (11) Å, b=6.4480 (4) Å, c=15.3202 (16) Å, β=105.990 (2) °, V=1074.23 (17) Å3, F (000)=592. The thermal decomposition behavior was investigated by differential scanning calorimetry (DSC) technology, and non-isothermal kinetic parameters were also calculated. Results indicate that it has a good thermal stability with the decomposition temperature above 190℃. The apparent activation energy are 210.6 kJ·mol-1 (Kissinger) and 207.9 kJ·mol-1 (Ozawa-Doyle), respectively, and the critical temperature of thermal explosion is 200.7℃. © 2016, Editorial Board of Chinese Chinese Journal of Energetic Materials.
