  The cohesive energies of solids calculated using mGLJ EOS proposed by Sun
Jiuxun (Sun Jiuxun, J. Phys.: Condens. Matter 17, L103 (2005)) are seen to be
erroneous. Also we observed that the thermodynamic properties calculated using
the mGLJ potential diverge for materials whose pressure derivative of bulk
modulus at equilibrium is less than 5. Thus the mGLJ potential cannot be used
in liquid state theories and molecular simulations to obtain thermodynamic
properties.
