An interesting 3D energetic metal - framework based Ag(I) ions and 3,4-diaminofurazan

As a new structural motif, an interesting 3D energetic metal–framework of silver ions and 3,4-diaminofurazan, [Ag⁺(daf)NO₃⁻]_n, is successfully synthesized and the structure is determined by single-crystal X-ray diffraction. The effects of hydrogen bond, coordination bond, adsorption and filling interactions make this compound have a high density (2.694 g·cm⁻³ at 293 K). The calculated detonation velocity and the sensitivities are all comparable with trinitrotoluene (TNT). The onset decomposition temperature is equal to hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), state-of-the-art explosive. This framework provides a potential superiority of E-MOFs for energetic materials.
