Ba2TbSnO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Pn-3 space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded to twelve equivalent O(1) atoms to form BaO12 cuboctahedra that share corners with twelve equivalent Ba(2)O12 cuboctahedra, faces with six equivalent Ba(2)O12 cuboctahedra, faces with four equivalent Tb(1)O6 octahedra, and faces with four equivalent Sn(1)O6 octahedra. In the second Ba site, Ba(2) is bonded to twelve equivalent O(1) atoms to form BaO12 cuboctahedra that share corners with four equivalent Ba(1)O12 cuboctahedra, corners with eight equivalent Ba(2)O12 cuboctahedra, faces with two equivalent Ba(1)O12 cuboctahedra, faces with four equivalent Ba(2)O12 cuboctahedra, faces with four equivalent Tb(1)O6 octahedra, and faces with four equivalent Sn(1)O6 octahedra. Tb(1) is bonded to six equivalent O(1) atoms to form TbO6 octahedra that share corners with six equivalent Sn(1)O6 octahedra, faces with two equivalent Ba(1)O12 cuboctahedra, and faces with six equivalent Ba(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 8°. Sn(1) is bonded to six equivalent O(1) atoms to form SnO6 octahedra that share corners with six equivalent Tb(1)O6 octahedra, faces with two equivalent Ba(1)O12 cuboctahedra, and faces with six equivalent Ba(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 8°. O(1) is bonded in a 2-coordinate geometry to one Ba(1), three equivalent Ba(2), one Tb(1), and one Sn(1) atom.
