A novel energetic coordination complex of [Co(AZT)2(H2O)4](HTNR)2•4H2O (AZT＝3-azido-1,2,4-triazole, TNR＝2,4,6-trinitro resorcinol) was prepared and characterized by elemental analysis and FT-IR spectroscopy. Single crystals of [Co(AZT)2(H2O)4](HTNR)2•4H2O were obtained through slow evaporation of a saturated water solution. The molecular structure was determined by X-ray single crystal diffraction. The crystal belongs to the triclinic system with a space group with crystal parameters of a＝7.1824 Å, b＝10.1812 Å, c＝13.115 Å, α＝98.046°, β＝105.367°, γ＝104.103°, V＝875.2 Å3, Z＝1. The thermal decomposition mechanism of [Co(AZT)2(H2O)4](HTNR)2•4H2O was predicted based on differential scanning calorimetry (DSC) and thermo-gravimetry-derivative thermo-gravimetry (TG-DTG) analyses. The kinetic parameters of the exothermic process of the compound were studied by Kissinger s, Starink s and Ozawa-Doyle s methods, with the apparent activation energy being 124.53, 124.82 and 125.55 kJ•mol－1, respectively. Sensitivity tests reveal that the title complex has good friction sensitivity.
