摘　　要：A novel energetic compound 3-（3,5-dimethylpyrazol-1-yl）-6-semicarbazide-1,2,4,5-tetrazine（DSTZ） was prepared and characterized by elemental analysis and Fourier transform infrared（FTIR） spectroscopy.The crystal structure was determined by X-ray single crystal diffraction technology.The crystal belongs to the monoclinic system with a P2 1 /c space group,a=0.9942（7） nm,b=0.5067（3） nm,c=1.1830（8） nm,β=109.616°,Z=2 and D c =1.475 g/cm 3.With extensive hydrogen bonds,the molecules were linked together to form a three-dimensional herringbone-like pattern.Thermal analysis of the compound was carried out via differential scanning calorimetry（DSC） and thermogravimetric-derivative thermogravimetry（TG-DTG）.Under a nitrogen atmosphere at a heating rate of 10 K/min,DSTZ decomposed directly in a range of 493―513 K.Only one intense exothermic process was observed and the decomposition products were all gaseous products.Conventional sensitivity properties were determined,showing that the title complex was insensitive to friction,impact and flame.A novel energetic compound 3-（3,5-dimethylpyrazol-1-yl）-6-semicarbazide-1,2,4,5-tetrazine（DSTZ） was prepared and characterized by elemental analysis and Fourier transform infrared（FTIR） spectroscopy.The crystal structure was determined by X-ray single crystal diffraction technology.The crystal belongs to the monoclinic system with a P2 1 /c space group,a=0.9942（7） nm,b=0.5067（3） nm,c=1.1830（8） nm,β=109.616°,Z=2 and D c =1.475 g/cm 3.With extensive hydrogen bonds,the molecules were linked together to form a three-dimensional herringbone-like pattern.Thermal analysis of the compound was carried out via differential scanning calorimetry（DSC） and thermogravimetric-derivative thermogravimetry（TG-DTG）.Under a nitrogen atmosphere at a heating rate of 10 K/min,DSTZ decomposed directly in a range of 493―513 K.Only one intense exothermic process was observed and the decomposition products were all gaseous products.Conventional sensitivity properties were determined,showing that the title complex was insensitive to friction,impact and flame.
