摘要：

A novel energetic complex [Ag2(DAT)4](NO3)2 (DAT=1,5-diaminotetrazole) was synthesized by using 1,5-diaminotetrazole (DAT) and AgNO3 as raw materials, and the yield was 86%.Its structure was characterized by elemental analysis and Fourier transform infrared (FT-IR) spectroscopy. The single crystal of the target complex was cultured and its structure was determined by X-ray single-crystal diffraction instrument. Its thermal decomposition behavior was investigated by differential scanning calorimetry (DSC). Its kinetic parameters (activation energies EK and EO) of non-isothermal reaction were calculated by Kissinger method and Ozawa method. Its critical temperature of thermal explosion Tb was calculated. Its constant-volume energy of combustion (Qv) was measured by using an oxygen bomb calorimeter. Its standard heat of formation was calculated. The impact, friction and flame sensitivities of the target complex were measured. Results show that the crystal of the target complex is monoclinic, space group P21/n with the cell parameters of a=6.8109(9) Å, b=19.654(3) Å, c=8.4510(11) Å, β=102.590(3)°, V=1104.1(3) Å3, Z=2, Dc =2.228 g·cm-3, F(000)=729. For the target complex, EK=204.9 kJ·mol-1,EO=202.8 kJ·mol-1, Tb=224.4℃, QV=-4177.59 kJ·mol-1, ΔfH298Θ=258.14 kJ·mol-1. The target complex is insensitive to impact and flame, but sensitive to friction. © 2016, Editorial Board of Chinese Chinese Journal of Energetic Materials. All right reserved.
