SrV4SnO12 crystallizes in the tetragonal P4/mmm space group. Sr(1) is bonded to four equivalent O(2) and eight equivalent O(1) atoms to form SrO12 cuboctahedra that share corners with four equivalent Sr(1)O12 cuboctahedra, corners with eight equivalent Sn(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 Sr(1)O12 cuboctahedra, and faces with two equivalent Sn(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Sn(1) is bonded to four equivalent O(3) and eight equivalent O(1) atoms to form SnO12 cuboctahedra that share corners with four equivalent Sn(1)O12 cuboctahedra, corners with eight equivalent Sr(1)O12 cuboctahedra, and faces with eight equivalent V(1)O6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one Sr(1), two equivalent V(1), and one Sn(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to two equivalent Sr(1) and two equivalent V(1) atoms. In the third O site, O(3) is bonded in a linear geometry to two equivalent V(1) and two equivalent Sn(1) atoms.
