High-Pressure Synthesis of Nitrogen-Rich Y(N₅)₃·N₂ Pentazolate with Perovskite Topology.

ABSTRACT: The discovery and stabilization of the cyclo-N₅⁻ anion have introduced a class of pentazolate compounds with significant potential as high-energy-density materials (HEDMs). This potential could be further enhanced by increasing the pentazolate-to-metal ratio. Here, we report the high-pressure, high-temperature synthesis and characterization of a novel yttrium pentazolate, Y(N₅)₃·N₂, which exhibits an exceptionally high nitrogen-to-metal ratio of 17:1. Y(N₅)₃·N₂ was synthesized from yttrium and nitrogen by laser heating to 3000 K at 125 GPa in a diamond anvil cell. Its crystal structure, a 3D nitrogen-inclusion metal-pentazolate framework, was solved and refined in situ using synchrotron single-crystal X-ray diffra
