Abstract

We investigate high-pressure phase diagrams of Pr–N compounds by proposing five stable structures (Pnma-PrN, I4/mmm-PrN2, C2/m-PrN3, P 1 ¯ -PrN4, and R3-PrN8) and two metastable structures ( P 1 ¯ -PrN6 and P 1 ¯ -PrN10). The P 1 ¯ -PrN6 with the N14-ring layer and R3-PrN8 with the N18-ring layer can be quenched to ambient conditions. For the P 1 ¯ -PrN10, the N22-ring layer structure transfers into infinite chains with the pressure quenched to ambient pressure. Remarkably, a novel polynitrogen hR8-N designed by the excision of Pr atoms from R3-PrN8 is obtained and can be quenched to ambient conditions. The N-rich structures of P 1 ¯ -PrN6, R3-PrN8, c-PrN10 and the solid pure nitrogen structure exhibit outstanding properties of energy density and explosive performance.
