The compound described by BaSmV4O12 crystallizes in the tetragonal P4/mmm space group. Ba(1) is bonded to four equivalent O(3) and eight equivalent O(1) atoms to form BaO12 cuboctahedra that share corners with four equivalent Ba(1)O12 cuboctahedra, corners with eight equivalent Sm(1)O12 cuboctahedra, and faces with eight equivalent V(1)O6 octahedra. Sm(1) is bonded to four equivalent O(2) and eight equivalent O(1) atoms to form SmO12 cuboctahedra that share corners with four equivalent Sm(1)O12 cuboctahedra, corners with eight equivalent Ba(1)O12 cuboctahedra, and faces with eight equivalent V(1)O6 octahedra. V(1) is bonded to one O(2), one O(3), and four equivalent O(1) atoms to form VO6 octahedra that share corners with six equivalent V(1)O6 octahedra, faces with two equivalent Ba(1)O12 cuboctahedra, and faces with two equivalent Sm(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-5°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one Ba(1), one Sm(1), and two equivalent V(1) atoms. In the second O site, O(2) is bonded in a distorted linear geometry to two equivalent Sm(1) and two equivalent V(1) atoms. In the third O site, O(3) is bonded in a distorted square co-planar geometry to two equivalent Ba(1) and two equivalent V(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
