Materials Data on Sr2CrOsO6 by Materials Project
Sr2CrOsO6 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Sr2+ is bonded to twelve equivalent O2- atoms to form SrO12 cuboctahedra that share corners with twelve equivalent SrO12 cuboctahedra, faces with six equivalent SrO12 cuboctahedra, faces with four equivalent CrO6 octahedra, and faces with four equivalent OsO6 octahedra. There are a spread of Sr–O bond distances ranging from 2.73–2.88 Å. Cr3+ is bonded to six equivalent O2- atoms to form CrO6 octahedra that share corners with six equivalent OsO6 octahedra and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 4°. All Cr–O bond lengths are 2.00 Å. Os5+ is bonded to six equivalent O2- atoms to form OsO6 octahedra that share corners with six equivalent CrO6 octahedra and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 4°. All Os–O bond lengths are 1.97 Å. O2- is bonded in a 2-coordinate geometry to four equivalent Sr2+, one Cr3+, and one Os5+ atom.
