Materials Data on Ba2CaTeO6 by Materials Project
Ba2CaTeO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Ba2+ is bonded to twelve equivalent O2- atoms to form BaO12 cuboctahedra that share corners with twelve equivalent BaO12 cuboctahedra, faces with six equivalent BaO12 cuboctahedra, faces with four equivalent CaO6 octahedra, and faces with four equivalent TeO6 octahedra. All Ba–O bond lengths are 3.01 Å. Ca2+ is bonded to six equivalent O2- atoms to form CaO6 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 Ca–O bond lengths are 2.30 Å. Te6+ is bonded to six equivalent O2- atoms to form TeO6 octahedra that share corners with six equivalent CaO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Te–O bond lengths are 1.96 Å. O2- is bonded in a distorted linear geometry to four equivalent Ba2+, one Ca2+, and one Te6+ atom.
