Abstract
We report the compressibility of the stoichiometric hexagonal \ensuremath{\delta} phase of MoN that is a well-known hard material that becomes superconducting below ${T}_{c}=12\mathrm{K}.$ The measured bulk modulus is ${K}_{0}=345(9)\mathrm{GPa}$ and ${K}_{0}^{\ensuremath{'}}=3.5(3).$ We also report the compressibility of the non-stoichiometric cubic $B1$ structured $\ensuremath{\gamma}\ensuremath{-}{\mathrm{Mo}}_{2}\mathrm{N}$ phase, that has a lower bulk modulus $[{K}_{0}=301(7)\mathrm{GPa},$ assuming ${K}_{0}^{\ensuremath{'}}=4].$ The difference in bulk modulus is due to the difference in structure and the cohesive energy between the two phases.
