Ba2SmWO6 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 Sm(1)O6 octahedra, and faces with four equivalent W(1)O6 octahedra. Sm(1) is bonded to six equivalent O(1) atoms to form SmO6 octahedra that share corners with six equivalent W(1)O6 octahedra and faces with eight equivalent Ba(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. W(1) is bonded to six equivalent O(1) atoms to form WO6 octahedra that share corners with six equivalent Sm(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 Sm(1), and one W(1) atom.
