Materials Data on Ba2GdSbO6 by Materials Project

Ba2GdSbO6 is High-temperature superconductor-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of four antimony molecules, four gadolinium molecules, and one BaO3 framework. In the BaO3 framework, Ba2+ is bonded to six equivalent O2- atoms to form corner-sharing BaO6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Ba–O bond lengths are 2.30 Å. O2- is bonded in a linear geometry to two equivalent Ba2+ atoms.

Materials Data on Ba2GdSbO6 by Materials Project

Ba2GdSbO6 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 GdO6 octahedra, and faces with four equivalent SbO6 octahedra. All Ba–O bond lengths are 3.04 Å. Gd3+ is bonded to six equivalent O2- atoms to form GdO6 octahedra that share corners with six equivalent SbO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Gd–O bond lengths are 2.27 Å. Sb5+ is bonded to six equivalent O2- atoms to form SbO6 octahedra that share corners with six equivalent GdO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Sb–O bond lengths are 2.02 Å. O2- is bonded in a distorted linear geometry to four equivalent Ba2+, one Gd3+, and one Sb5+ atom.
