Ba2PaTbO6 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 Pa(1)O6 octahedra, and faces with four equivalent Tb(1)O6 octahedra. Pa(1) is bonded to six equivalent O(1) atoms to form PaO6 octahedra that share corners with six equivalent Tb(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Tb(1) is bonded to six equivalent O(1) atoms to form TbO6 octahedra that share corners with six equivalent Pa(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 distorted linear geometry to four equivalent Ba(1), one Pa(1), and one Tb(1) atom.
