Materials Data on Ba2LaSbO6 by Materials Project

Ba2LaSbO6 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Ba2+ is bonded in a 12-coordinate geometry to twelve equivalent O2- atoms. There are a spread of Ba–O bond distances ranging from 2.84–3.36 Å. La3+ is bonded to six equivalent O2- atoms to form LaO6 octahedra that share corners with six equivalent SbO6 octahedra. The corner-sharing octahedral tilt angles are 14°. All La–O bond lengths are 2.37 Å. Sb5+ is bonded to six equivalent O2- atoms to form SbO6 octahedra that share corners with six equivalent LaO6 octahedra. The corner-sharing octahedral tilt angles are 14°. All Sb–O bond lengths are 2.03 Å. O2- is bonded in a 2-coordinate geometry to four equivalent Ba2+, one La3+, and one Sb5+ atom.

Materials Data on Ba2LaSbO6 by Materials Project

Ba2LaSbO6 is (Cubic) Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with twelve equivalent BaO12 cuboctahedra, faces with six equivalent BaO12 cuboctahedra, faces with four equivalent LaO6 octahedra, and faces with four equivalent SbO6 octahedra. There are a spread of Ba–O bond distances ranging from 2.98–3.23 Å. La3+ is bonded to six O2- atoms to form LaO6 octahedra that share corners with six equivalent SbO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 3–7°. All La–O bond lengths are 2.36 Å. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with six equivalent LaO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedra tilt angles range from 3–7°. All Sb–O bond lengths are 2.02 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to four equivalent Ba2+, one La3+, and one Sb5+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to four equivalent Ba2+, one La3+, and one Sb5+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to four equivalent Ba2+, one La3+, and one Sb5+ atom.
