Sr2SnFeO6 is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal P4/mmm space group. Sr(1) is bonded to four equivalent O(1), four equivalent O(2), and four equivalent O(3) atoms to form SrO12 cuboctahedra that share corners with twelve equivalent Sr(1)O12 cuboctahedra, faces with six equivalent Sr(1)O12 cuboctahedra, faces with four equivalent Fe(1)O6 octahedra, and faces with four equivalent Sn(1)O6 octahedra. Fe(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form FeO6 octahedra that share corners with two equivalent Sn(1)O6 octahedra, corners with four equivalent Fe(1)O6 octahedra, and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Sn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SnO6 octahedra that share corners with two equivalent Fe(1)O6 octahedra, corners with four equivalent Sn(1)O6 octahedra, and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to four equivalent Sr(1), one Fe(1), and one Sn(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to four equivalent Sr(1) and two equivalent Sn(1) atoms. In the third O site, O(3) is bonded to four equivalent Sr(1) and two equivalent Fe(1) atoms to form a mixture of distorted corner, edge, and face-sharing OSr4Fe2 octahedra. The corner-sharing octahedra are not tilted.
