Materials Data on Ba2CaBiO6 by Materials Project
Ba2CaBiO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. 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 CaO6 octahedra, and faces with four equivalent BiO6 octahedra. All Ba–O bond lengths are 3.10 Å. Ca is bonded to six equivalent O atoms to form CaO6 octahedra that share corners with six equivalent BiO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ca–O bond lengths are 2.27 Å. Bi is bonded to six equivalent O atoms to form BiO6 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 Bi–O bond lengths are 2.12 Å. O is bonded in a distorted linear geometry to four equivalent Ba, one Ca, and one Bi atom.
