Ba2GdTaO6 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 TaO6 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 TaO6 octahedra and faces with eight equivalent BaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Gd–O bond lengths are 2.29 Å. Ta5+ is bonded to six equivalent O2- atoms to form TaO6 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 Ta–O bond lengths are 2.01 Å. O2- is bonded in a distorted linear geometry to four equivalent Ba2+, one Gd3+, and one Ta5+ atom.
