A new 3D Ag()-based high-energy metal organic frameworks (HE-MOFs): synthesis, crystal structure and explosive performance

A new 3D Ag( i )-based HE-MOFs, [Ag 2 (TABT)(NO 3 ) 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, 1 H-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. A new 3D HE-MOF, [Ag 2 (TABT)(NO 3 ) 2 ] n , where TABT represents 4,4′,5,5′-tetraamine-3,3′-bis-1,2,4-triazole, was synthesized by hydrothermal method, exhibiting high density, good thermostability, insensitivity and relative high detonation performance.
