摘要

An energetic metal–organic framework (EMOF) [Ag _(2) (5-ATZ)(N _(3) )] ( 1 ) was hydrothermally prepared and structurally characterized by single crystal X-ray diffraction analysis. 1 features a compacted three-dimensional framework structure and possesses the highest density ( ρ = 3.4 g cm ~(?3) ) in the known energetic compounds, in which each 5-ATZ ligand possesses a μ _(4) -1,2,3,4 coordination mode and each azide group adopts a rare μ _(4) -1,1,1,3 bridging mode. 1 exhibits a considerably high thermal stability, with a thermal decomposition temperature of about 300.0 °C, and insensitivity to external stimuli. Remarkably, the kinetic triplets (the apparent activation energy ( E _(a) ), the preexponential factor ( A ) and the mechanism function ( f ( α ))) are discussed in detail. In addition, the energetic performance and the catalytic effect of 1 on the thermal decomposition of hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) were also examined.
