Title: Materials Data on BaLa2(CoO3)3 by Materials Project

Abstract

BaLa2(CoO3)3 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with six equivalent BaO12 cuboctahedra, corners with six equivalent LaO12 cuboctahedra, faces with six equivalent LaO12 cuboctahedra, and faces with eight CoO6 octahedra. There are six shorter (2.76 Å) and six longer (2.84 Å) Ba–O bond lengths. La3+ is bonded to twelve O2- atoms to form LaO12 cuboctahedra that share corners with three equivalent BaO12 cuboctahedra, corners with nine equivalent LaO12 cuboctahedra, faces with three equivalent BaO12 cuboctahedra, faces with three equivalent LaO12 cuboctahedra, and faces with eight CoO6 octahedra. There are a spread of La–O bond distances ranging from 2.64–2.76 Å. There are two inequivalent Co+3.33+ sites. In the first Co+3.33+ site, Co+3.33+ is bonded to six equivalent O2- atoms to form CoO6 octahedra that share corners with six equivalent CoO6 octahedra, faces with two equivalent BaO12 cuboctahedra, and faces with six equivalent LaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 6°. All Co–O bond lengths are 1.94 Å. In the second Co+3.33+ site, Co+3.33+ is bonded to six O2- atoms to form CoO6 octahedra that share cornersmore » with six CoO6 octahedra, faces with three equivalent BaO12 cuboctahedra, and faces with five equivalent LaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 0–6°. There is three shorter (1.94 Å) and three longer (1.96 Å) Co–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to one Ba2+, three equivalent La3+, and two Co+3.33+ atoms. In the second O2- site, O2- is bonded in a distorted linear geometry to two equivalent Ba2+, two equivalent La3+, and two equivalent Co+3.33+ atoms.« less
