Materials Data on Sr2LaCoO6 by Materials Project

Abstract

Sr2LaCoO6 is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sr is bonded to twelve O 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 CoO6 octahedra. There are four shorter (2.95 Å) and eight longer (2.96 Å) Sr–O bond lengths. La is bonded to six O atoms to form LaO6 octahedra that share corners with six equivalent CoO6 octahedra and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There are two shorter (2.28 Å) and four longer (2.31 Å) La–O bond lengths. Co is bonded to six O atoms to form CoO6 octahedra that share corners with six equivalent LaO6 octahedra and faces with eight equivalent SrO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. There is four shorter (1.86 Å) and two longer (1.90 Å) Co–O bond length. There are two inequivalent O sites. In the first O site, O is bonded in a distorted linear geometry to four equivalent Sr, one La, and one Co atom. In the second O site, O is bonded in a distorted linear geometry to four equivalent Sr, one La, and one Co atom.
