Abstract
Two energetic compounds, [Zn(H2O)6](PA) 2·3H2O (1) and Zn(ATZ)3](PA) 2·2.5H2O]n (2), were synthesized based on 4-amino- 1,2,4-triazole (ATZ) and picrate (PA), and characterized by elemental analysis and Fourier transform infrared (FT-IR) spectroscopy. The crystallographic data showed that the crystals of 1 and 2 belong to the monoclinic space group P21/n and the triclinic space group P1 , respectively. Furthermore, the ZnII cations are six-coordinated with six oxygen atoms from crystal water molecules for 1 and six nitrogen atoms from ATZ for 2, and exhibit distorted octahedral configurations. Thermal decomposition mechanisms were determined based on differential scanning calorimeter (DSC) curve corresponding to thermogravimetry- derivative thermogravimetry (TG-DTG) curves and kinetic parameters of the first exothermic process were studied by using Kissinger's and Ozawa's method. The energies of the impact sensitivities were 27.8 J for 2 and far greater than 29.4 J for 1. In addition, the experiment found the heats of combustion were -6.53 MJ·kg-1 for 1 and -11.33 MJ·kg-1 for 2 by oxygen bomb calorimeter. Therefore, compound 2 can improve the explosion performance and can maybe regarded as the less toxicity energy additive for the explosives and propellant formulations.
