Abstract
A novel energetic coordination complex of [Mn (AZT)2 (H2O) 4] (HTNR) 2·4H2O (AZT=3-azido-1,2,4- triazole, HTNR=2,4,6-trinitro resorcinol) was prepared by the reaction between the acidic manganese (II) salt of 2,4,6-trinitro resorcinol and AZT in an aqueous solution. The complex was characterized by elemental analysis and FTIR spectroscopy. The molecular structure was determined by X-ray single crystal diffraction. The crystal belongs to the triclinic systemwith a P1 space group. The central manganese(II) cation has a slightly distorted octahedron feature. Three-dimension networks were formed and the layers are linked by extensive hydrogen bonding. The thermal decomposition mechanism of [Mn(AZT)2 (H2O)4](HTNR)2·4H2O was predicted based on differential scanning calorimetry (DSC) and thermogravimetry-derivative thermogravimetry (TG-DTG) analyses. One endothermic peak and three exothermic peaks are present during the thermal decomposition process with the final residue at 600 °C being MnO and MnO2. The kinetic parameters of the exothermic process for the complex were studied using Kissinger's and Ozawa-Doyle's methods. Furthermore, impact sensitivity, flame sensitivity, and friction sensitivity tests reveal that the title complex is sensitive and selective towards external stimulants.
