Materials Data on Ba2LiIO6 by Materials Project
LiBa2O6I 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 IO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Li–O bond lengths are 2.24 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 IO6 octahedra. All Ba–O bond lengths are 2.94 Å. O is bonded to one Li, four equivalent Ba, and one I atom to form a mixture of distorted edge, face, and corner-sharing OBa4LiI octahedra. The corner-sharing octahedra tilt angles range from 0–60°. The O–I bond length is 1.91 Å. I is bonded to six equivalent O atoms to form IO6 octahedra that share corners with six equivalent LiO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°.
