Ba2BiTaO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Ba(1) is bonded to twelve equivalent O(1) atoms to form BaO12 cuboctahedra that share corners with twelve equivalent Ba(1)O12 cuboctahedra, faces with six equivalent Ba(1)O12 cuboctahedra, faces with four equivalent Ta(1)O6 octahedra, and faces with four equivalent Bi(1)O6 octahedra. Ta(1) is bonded to six equivalent O(1) atoms to form TaO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Bi(1) is bonded to six equivalent O(1) atoms to form BiO6 octahedra that share corners with six equivalent Ta(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a 6-coordinate geometry to four equivalent Ba(1), one Ta(1), and one Bi(1) atom.
