High-pressure synthesis of ultraincompressible hard rhenium nitride pernitride Re${}_2$(N${}_2$)N${}_2$ stable at ambient conditions

Maxim Bykov, Stella Chariton, Hongzhan Fei +17

Here we report the synthesis of metallic, ultraincompressible (bulk modulus $K_0$ = 428(10) GPa) and very hard (nanoindentation hardness 36.7(8) GPa) rhenium (V) nitride pernitri…
