Materials Data on Ba2TbIrO6 by Materials Project

Abstract

Ba2TbIrO6 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 TbO6 octahedra, and faces with four equivalent IrO6 octahedra. All Ba–O bond lengths are 3.00 Å. Tb3+ is bonded to six equivalent O2- atoms to form TbO6 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 Tb–O bond lengths are 2.24 Å. Ir5+ is bonded to six equivalent O2- atoms to form IrO6 octahedra that share corners with six equivalent TbO6 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. O2- is bonded in a distorted linear geometry to four equivalent Ba2+, one Tb3+, and one Ir5+ atom.
