N2 - This study conducted a systematic thermal safety assessment of two novel energetic coordination complexes (ECCs) based on the nitrogen-rich ligand 1-aminotriazole (1-ATRI): Cu(H2O)2(1-ATRI)4(ClO4)2 and Co(1-ATRI)6(ClO4)2. Utilizing a multi-technique strategy combining thermogravimetric analysis (TG), differential scanning calorimetry (DSC), and accelerating rate calorimetry (ARC), we developed a robust predictive framework for the thermal safety of ECCs. This approach enabled a systematic investigation of the thermal decomposition behavior, reaction kinetics, and thermal runaway risk of the complexes. Kinetic analysis was performed using isoconversional methods and model-fitting approaches. These analyses elucidated the decomposition mechanisms and provided key kinetic parameters. Adiabatic calorimetry delivered critical safety parameters characterizing thermal hazards, including the self-accelerating decomposition temperature (SADT) and the time to maximum rate under adiabatic conditions (TMRad). The results demonstrate that both complexes exhibit favorable thermal stability. However, they also present significant thermal hazards, necessitating the implementation of stringent safety management protocols. This research provides a theoretical foundation for their potential application as replacements for traditional energetic materials in propellants and pyrotechnics, thereby advancing the sustainable utilization of this class of complexes.
