摘要：

(Figure Presented) Shear innovation: By analyzing the crystallographic shear (CS) structures of "Pb2Fe2O5" (see picture; spheres Pb, polyhedra FeO6/FeO5), 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. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
