Azide-Based High-Energy Metal-Organic Framework with Enhanced Thermal Stability

<p>We report the synthesis of Zn(C6H4N5)N3, a new three-dimensional metal-organic framework (MOF) that exhibits strong energetic properties with high thermostability. The compound is synthesized by the hydrothermal method with <i>in situ</i> ligand formation under controlled pH. Structural characterization is carried out by single-crystal XRD, elemental analysis and FTIR. Energetic properties are obtained from TGA and DSC measurements. This novel MOF structure is thermally stable up to 345 C and its heat of detonation is -400$ kJ/g. The measured velocity and pressure of detonation are 4.66 km/s and 9.99 GPa, respectively.</p>
