Materials Data on Ba2BiIrO6 by Materials Project

Ba2BiIrO6 is Orthorhombic Perovskite-derived structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Ba2+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Ba–O bond distances ranging from 2.77–3.36 Å. Ir5+ is bonded to six O2- atoms to form IrO6 octahedra that share corners with six equivalent BiO6 octahedra. The corner-sharing octahedra tilt angles range from 11–17°. There are two shorter (2.00 Å) and four longer (2.01 Å) Ir–O bond lengths. Bi3+ is bonded to six O2- atoms to form BiO6 octahedra that share corners with six equivalent IrO6 octahedra. The corner-sharing octahedra tilt angles range from 11–17°. There are two shorter (2.32 Å) and four longer (2.33 Å) Bi–O bond lengths. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 6-coordinate geometry to four equivalent Ba2+, one Ir5+, and one Bi3+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to four equivalent Ba2+, one Ir5+, and one Bi3+ atom. In the third O2- site, O2- is bonded in a 5-coordinate geometry to four equivalent Ba2+, one Ir5+, and one Bi3+ atom.

Materials Data on Ba2BiIrO6 by Materials Project

Ba2BiIrO6 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 IrO6 octahedra, and faces with four equivalent BiO6 octahedra. All Ba–O bond lengths are 3.04 Å. Ir5+ is bonded to six equivalent O2- atoms to form IrO6 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 Ir–O bond lengths are 1.99 Å. Bi3+ is bonded to six equivalent O2- atoms to form BiO6 octahedra that share corners with six equivalent IrO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Bi–O bond lengths are 2.30 Å. O2- is bonded in a distorted linear geometry to four equivalent Ba2+, one Ir5+, and one Bi3+ atom.
