Reciprocal space Brillouin-zone (BZ) integrals were approximated with a special k-points sampling . Properties pertaining to the mechanical stability and hardness were derived from the sets of elastic constants. Besides, we inferred dynamic stability from the phonons computed using the harmonic approximation. The phonon band structures along the direction of the tetragonal Brillouin zone were subsequently obtained using the "Phonopy" interface code . The electronic band structure was also obtained using DFT-based Augmented Spherical Wave (ASW) method .
