It is demonstrated that the crystalline structure of MgGeN$_2$ can be reduced to the superposition of “approximated” high-symmetry Bravais sublattices by shifting atoms in a unit cell within the range of 5% of the lattice constant. The superimposed Brillouin zones were plotted for crystal lattices and sublattices. The computational results are presented for the electronic structure of MgGeN$_2$ in terms of the theory of the density function. The influence of “hidden” symmetry in this crystal on zone spectra is described.
