Synthesis of AgN₅ and its extended 3D energetic framework.

ABSTRACT: The pentazolate anion, as a polynitrogen species, holds great promise as a high-energy density material for explosive or propulsion applications. Designing pentazole complexes that contain minimal non-energetic components is desirable in order to increase the material's energy density. Here, we report a solvent-free pentazolate complex, AgN₅, and a 3D energetic-framework, [Ag(NH₃)₂]⁺[Ag₃(N₅)₄]-, constructed from silver and cyclo-N₅-. The complexes are stable up to 90 °C and only Ag and N₂ are observed as the final decomposition products. Efforts to isolate pure AgN₅ were unsuccessful due to partial photolytical and/or thermal-decomposition to AgN₃. Convincing evidence fo
