Shear innovation : By analyzing the crystallographic shear (CS) structures of “Pb 2 Fe 2 O 5 ” (see picture; spheres Pb, polyhedra FeO 6 /FeO 5 ), new building principles are derived for perovskite‐based compounds containing cations with a lone electron pair in the A sites of the perovskite structure. The chemical composition can be adjusted by varying the orientation of the CS planes and the thickness of the perovskite slabs between the planes.
