Abstract
${\mathrm{WN}}_{6}$ phase discovered at 126--165 GPa after heating of W in nitrogen. XRD refinements reveal a unit cell in space group $R\overline{3}m$ which is consistent with the ${\mathrm{WN}}_{6}$ structure with armchairlike hexazine (${\mathrm{N}}_{6}$) rings, while strong ${A}_{1g}$ Raman mode confirms its $\mathrm{N}─\mathrm{N}$ single bonds. Density functional theory (DFT) calculations reveal balanced contributions of attractive interactions between W and covalent ${\mathrm{N}}_{6}$ rings, and repulsions between ${\mathrm{N}}_{6}$ rings that make ${\mathrm{WN}}_{6}$ ultrastiff and tough. The ${\mathrm{WN}}_{6}$ phase displays long bond lengths in the nearest N-N and pressure-enhanced electronic band gap, which pave the way for finding novel nitrides.
