N2 - A novel solvent-free energetic coordination polymer [Ag(3,4-dnp)] was performed by dehydration. The structure was confirmed by single-crystal X-ray crystallography and the Ag(I) ions are coordinated in bidentate-bridging mode. The results of thermal analysis (thermogravimetric and accelerating rate calorimeter) show that this compound has higher thermal stability than that of the traditional CHON-containing energetic materials, RDX, HMX and CL-20. The detonation velocity and detonation pressure of [Ag(3,4-dnp)] are 5.532 km s−1, 15.88 GPa, respectively, which is lower than that HMX, RDX and TNT, and comparable with the 2D MOFs [Ag(Mtta)] based on the Ag ions and 5-methyl tetrazole. The impact and friction sensitivities of this compound are infinitely close to RDX, state-of-the-art explosive. The coordination polymers based on metal ions and nitropyrazole are promising potential as energetic materials.
