Materials Data on BaSr4(FeO2)5 by Materials Project
Abstract
BaSr4(FeO2)5 crystallizes in the monoclinic P2/m space group. The structure is three-dimensional. Ba2+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Ba–O bond distances ranging from 2.72–2.82 Å. There are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.64–2.76 Å. In the second Sr2+ site, Sr2+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.64–2.73 Å. There are three inequivalent Fe2+ sites. In the first Fe2+ site, Fe2+ is bonded in a square co-planar geometry to four O2- atoms. There are a spread of Fe–O bond distances ranging from 2.04–2.07 Å. In the second Fe2+ site, Fe2+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. All Fe–O bond lengths are 2.04 Å. In the third Fe2+ site, Fe2+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.04 Å) and two longer (2.07 Å) Fe–O bond lengths. There are six inequivalent O2- sites. In the first O2-more »
