Materials Data on Sr4Cr3O10 by Materials Project
Abstract
Sr4Cr3O10 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.52–2.74 Å. In the second Sr2+ site, Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with eight equivalent SrO12 cuboctahedra, faces with five equivalent SrO12 cuboctahedra, and faces with eight CrO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.72–2.75 Å. There are two inequivalent Cr4+ sites. In the first Cr4+ site, Cr4+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with five CrO6 octahedra and faces with four equivalent SrO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–5°. There are a spread of Cr–O bond distances ranging from 1.94–2.08 Å. In the second Cr4+ site, Cr4+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with six CrO6 octahedra and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There is two shorter (1.88 Å) and four longer (1.94 Å) Cr–O bondmore »

The corner-sharing octahedral tilt angles are 7°. In the second O2- site, O2- is bonded in a distorted linear geometry to four Sr2+ and two equivalent Cr4+ atoms. In the third O2- site, O2- is bonded in a distorted linear geometry to four equivalent Sr2+ and two Cr4+ atoms. In the fourth O2- site, O2- is bonded in a distorted linear geometry to four equivalent Sr2+ and two equivalent Cr4+ atoms.},
