Summary:Recently, Ghoohestani et al (2014 Phys. Scr. 89 035801) published a paper in which they investigated the effect of the pressure on structural, optical and electronic properties of copper nitride (Cu sub(3)N) in its phase cubic anti-ReO sub(3) structure. After studying the article I found that there are some numerical mistakes in the density, longitudinal, transverse and average elastic wave velocities, and the Debye temperature. These mistakes are certainly due to the inaccurate application of the formula used to calculate the density. In the present comment, we recalculate and we give the correct numerical values of previous quantities, based on the lattice constants and the elastic constants obtained in their work.
