Figure 3
The outer part shows the structural changes between Sc₂Sb and Dy₉Sb₅O₅ (projection along [001]). The middle part represents the twinning phenomena using the example of Dy₉Sb₅O₅. The unit cells, and the directions of the unit-cell axes of Sc₂Sb and the two differently oriented twinning domains of Dy₉Sb₅O₅, are drawn in together with the mirror plane [m = (310)], which transforms both domains into each other. [DySb] layers are displayed in the ball-and-stick mode, and the [Dy₄O₅] part is presented as polyhedra (see text).
