(color online) The crystal structures of (a) the kesterite and (b) Cu/Zn partially disordered kesterite Cu₂ZnSnS₄. Partially disordered means that the Cu/Zn disordered occupation exists only in the (001) CuZn layers, so the symmetry of the crystal lattice is also I-4, equivalent to that of the stannite structure.
