Materials Data on Ba2LiTeO6 by Materials Project

Abstract

LiBa2TeO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Li is bonded to six equivalent O atoms to form LiO6 octahedra that share corners with six equivalent TeO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Li–O bond lengths are 2.22 Å. Ba is bonded to twelve equivalent O atoms to form BaO12 cuboctahedra that share corners with twelve equivalent BaO12 cuboctahedra, faces with six equivalent BaO12 cuboctahedra, faces with four equivalent LiO6 octahedra, and faces with four equivalent TeO6 octahedra. All Ba–O bond lengths are 2.95 Å. Te is bonded to six equivalent O atoms to form TeO6 octahedra that share corners with six equivalent LiO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Te–O bond lengths are 1.95 Å. O is bonded in a distorted linear geometry to one Li, four equivalent Ba, and one Te atom.
