Materials Data on BaLa3TiCr3O12 by Materials Project
BaLa3TiCr3O12 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form distorted BaO12 cuboctahedra that share corners with two equivalent BaO12 cuboctahedra, faces with two equivalent BaO12 cuboctahedra, faces with four equivalent TiO6 octahedra, and faces with four equivalent CrO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.66–3.21 Å. There are three inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 12-coordinate geometry to eleven O2- atoms. There are a spread of La–O bond distances ranging from 2.43–2.97 Å. In the second La3+ site, La3+ is bonded in a 3-coordinate geometry to ten O2- atoms. There are a spread of La–O bond distances ranging from 2.42–2.83 Å. In the third La3+ site, La3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.39–2.82 Å. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with four equivalent CrO6 octahedra, and faces with four equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 10–16°. There is two shorter (1.95 Å) and four longer (2.00 Å) Ti–O bond length. There are two inequivalent Cr3+ sites. In the first Cr3+ site, Cr3+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with two equivalent TiO6 octahedra, corners with four CrO6 octahedra, and faces with two equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 8–22°. There are a spread of Cr–O bond distances ranging from 1.99–2.03 Å. In the second Cr3+ site, Cr3+ is bonded to six O2- atoms to form corner-sharing CrO6 octahedra. The corner-sharing octahedra tilt angles range from 20–22°. There are a spread of Cr–O bond distances ranging from 1.98–2.01 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Ba2+, two La3+, one Ti4+, and one Cr3+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Ba2+, one La3+, and two equivalent Ti4+ atoms. In the third O2- site, O2- is bonded in a 5-coordinate geometry to three La3+ and two Cr3+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Ba2+, two La3+, one Ti4+, and one Cr3+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Ba2+, three La3+, and two equivalent Cr3+ atoms. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to one Ba2+, three La3+, and two equivalent Cr3+ atoms. In the seventh O2- site, O2- is bonded in a 5-coordinate geometry to three La3+ and two Cr3+ atoms. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to three La3+ and two equivalent Cr3+ atoms.
