Variation of structural parameters of the Fe3+O6 octahedron between 90 and 900 K. (a) average Fe3+—O bond length; (b) selected individual Fe3+—O bond lengths; (c) bond-length distortion parameter BLD; (d) average of the O—O edges, shared with other topological units 〈es〉, right-hand scale compared with the average of the O—O unshared edges 〈eu〉, left-hand scale; (e) interatomic Fe—Fe distance along the b axis (left-hand) and the a axis (right-hand scale); (f) interatomic distance Fe—Cu as a function of temperature; for clarity error bars are not shown for Fe—O8 in (b) and 〈es〉 in (d).
