ABSTRACT

Two novel energetic ionic and coordination frameworks based on 3, 5-dinitropyrazole (3, 5-DNP) were prepared under the facile reaction conditions. They were characterized by FT-IR spectroscopy, Raman spectrum, single-crystal X-ray analysis and differential scanning calorimetry thermal analysis (DSC). Hirshfeld analysis showed that they both presented strong hydrogen-bond intermolecular interactions. Thermal properties and the nonisothermal thermokinetic parameters were obtained by differential scanning calorimeter (DSC) as well as Kissinger, Ozawa and Starink methods. The two energetic materials exhibit excellent thermal stabilities ([DNP] NH (Et)₃: Tm=251℃, Td=377℃; Cu [DNP]₂[H₂O]₂: Td=350℃). They can be potential candidates for heat-resistant energetic materials for military uses.
