A new 3D Ag(I)-based HE-MOFs, [Ag₂(TABT)(NO₃)₂]_n, where TABT represents 4,4′,5,5′-tetraamine-3,3′-bis-1,2,4-triazole, was synthesized and fully characterized by single-crystal X-ray diffraction, IR, ¹H-NMR and elemental analyses. Its thermal behaviors were investigated by thermogravimetry and differential scanning calorimetry (TG-DSC) techniques while the thermo-kinetic parameters of exothermic process were calculated by Kissinger and Ozawa methods. The results indicate that the compound possesses an excellent thermal stability with a high decomposition temperature up to 301.2 °C. In addition, its detonation properties and sensitivity suggest that the title Ag-based salt can be used as a potential explosive.
