Materials Data on Sr4Co3ReO12 by Materials Project
Sr4Co3ReO12 is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Sr2+ is bonded to twelve O2- atoms to form SrO12 cuboctahedra that share corners with twelve equivalent SrO12 cuboctahedra, faces with six equivalent SrO12 cuboctahedra, faces with two equivalent ReO6 octahedra, and faces with six CoO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.65–2.94 Å. Re7+ is bonded to six O2- atoms to form ReO6 octahedra that share corners with six CoO6 octahedra and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Re–O bond lengths are 1.89 Å. There are three inequivalent Co3+ sites. In the first Co3+ site, Co3+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent CoO6 octahedra, corners with four equivalent ReO6 octahedra, and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There is two shorter (1.86 Å) and four longer (2.06 Å) Co–O bond length. In the second Co3+ site, Co3+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent ReO6 octahedra, corners with four equivalent CoO6 octahedra, and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.01 Å) and two longer (2.05 Å) Co–O bond lengths. In the third Co3+ site, Co3+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six CoO6 octahedra and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (1.94 Å) and two longer (2.08 Å) Co–O bond lengths. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to four equivalent Sr2+ and two Co3+ atoms. In the second O2- site, O2- is bonded in a distorted linear geometry to four equivalent Sr2+, one Re7+, and one Co3+ atom. In the third O2- site, O2- is bonded to four equivalent Sr2+ and two Co3+ atoms to form a mixture of distorted face, edge, and corner-sharing OSr4Co2 octahedra. The corner-sharing octahedral tilt angles are 0°. In the fourth O2- site, O2- is bonded in a distorted linear geometry to four equivalent Sr2+, one Re7+, and one Co3+ atom.
