Octahedral Tilting in Perovskites. I. Geometrical Considerations

Woodward, P. M.·1997·Acta Crystallographica Section B Structural Science

Abstract

The 23 Glazer tilt systems describing octahedral tilting in perovskites have been investigated. It is shown that in tilt systems a + a + a −, a + b + b −, a + a + c −, a + b + c −, a 0 b + b − and a 0 b + c − it is not possible to link together a three-dimensional network of perfectly rigid octahedra. In these tilt systems small distortions of the octahedra must occur. The magnitude of the distortions in the a + a + a − and a 0 b + b − tilt systems are estimated. A table of predicted space groups for ordered perovskites, A 2 MM′O 6, for all 23 tilt systems is also given.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
