Materials Data on CaLa(CoO3)2 by Materials Project

Abstract

CaLa(CoO3)2 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ca2+ is bonded to twelve equivalent O2- atoms to form CaO12 cuboctahedra that share corners with twelve equivalent CaO12 cuboctahedra, faces with six equivalent LaO12 cuboctahedra, and faces with eight equivalent CoO6 octahedra. All Ca–O bond lengths are 2.69 Å. La3+ is bonded to twelve equivalent O2- atoms to form LaO12 cuboctahedra that share corners with twelve equivalent LaO12 cuboctahedra, faces with six equivalent CaO12 cuboctahedra, and faces with eight equivalent CoO6 octahedra. All La–O bond lengths are 2.69 Å. Co+3.50+ is bonded to six equivalent O2- atoms to form CoO6 octahedra that share corners with six equivalent CoO6 octahedra, faces with four equivalent CaO12 cuboctahedra, and faces with four equivalent LaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Co–O bond lengths are 1.90 Å. O2- is bonded in a distorted linear geometry to two equivalent Ca2+, two equivalent La3+, and two equivalent Co+3.50+ atoms.
