Various models fitted to the cuboctahedra found in four perovskite structure types and their respective elpasolite counterparts. Each structure type is represented by an array of crystal structures belonging to it. Each individual distortion δ was first divided by the distortion of the Archimedean cuboctahedron model fitted to the same coordination environment. Thus the arithmetic mean of all values generated was then taken for each combination of a model and a structure type in order to obtain a data point shown in the diagram. See the supporting information for a discussion of the methodology applied in this plot. |
