Materials Data on Sr5Fe4CoO10 by Materials Project
Sr5Fe4CoO10 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. there are three inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.65 Å) and four longer (2.70 Å) Sr–O bond lengths. In the second Sr2+ site, Sr2+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.66 Å) and four longer (2.69 Å) Sr–O bond lengths. In the third Sr2+ site, Sr2+ is bonded in a body-centered cubic geometry to eight equivalent O2- atoms. All Sr–O bond lengths are 2.67 Å. There are two inequivalent Fe2+ sites. In the first Fe2+ site, Fe2+ is bonded in a rectangular see-saw-like geometry to four equivalent O2- atoms. All Fe–O bond lengths are 2.02 Å. In the second Fe2+ site, Fe2+ is bonded in a rectangular see-saw-like geometry to four equivalent O2- atoms. All Fe–O bond lengths are 2.02 Å. Co2+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Co–O bond lengths are 2.02 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent Sr2+ and two equivalent Co2+ atoms to form a mixture of corner, edge, and face-sharing OSr4Co2 octahedra. The corner-sharing octahedra tilt angles range from 0–65°. In the second O2- site, O2- is bonded to four Sr2+ and two equivalent Fe2+ atoms to form distorted OSr4Fe2 octahedra that share corners with fourteen OSr4Co2 octahedra, edges with four OSr4Co2 octahedra, and faces with four equivalent OSr4Fe2 octahedra. The corner-sharing octahedra tilt angles range from 1–65°. In the third O2- site, O2- is bonded to four Sr2+ and two equivalent Fe2+ atoms to form a mixture of corner, edge, and face-sharing OSr4Fe2 octahedra. The corner-sharing octahedra tilt angles range from 0–65°.
