Figure 5
Group–subgroup relationship between the wurtzite subgroup Cmc21 and the β-NaFeO2-type as well as the α-LiSiON-type structures. Structure representations of the α-LiSiON type (a) (Laurent et al., 1981  ) and the β-NaFeO2 type (b) (Häusler, Neudert et al., 2017) are drawn as general views with atoms as generic spheres. An origin shift (0, 0, −0.5) was applied to the coordinates in the documented structure of LiSiON (Laurent et al., 1981) to highlight the group–subgroup relationship. We note that the orientation of the polar axis c is inverted in the documented structures with respect to the group–subgroup derived one. |
