Materials Data on Sr2LaCrO6 by Materials Project

Abstract

Sr2CrLaO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m 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 LaO6 octahedra, and faces with four equivalent CrO6 octahedra. All Sr–O bond lengths are 2.98 Å. La3+ is bonded to six equivalent O2- atoms to form LaO6 octahedra that share corners with six equivalent CrO6 octahedra and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All La–O bond lengths are 2.31 Å. Cr5+ is bonded to six equivalent O2- atoms to form CrO6 octahedra that share corners with six equivalent LaO6 octahedra and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Cr–O bond lengths are 1.89 Å. O2- is bonded in a distorted linear geometry to four equivalent Sr2+, one La3+, and one Cr5+ atom.
