Sr2SnFeO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Sr(1) is bonded to twelve equivalent O(1) 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 six equivalent O(1) atoms to form FeO6 octahedra that share corners with six equivalent Sn(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Sn(1) is bonded to six equivalent O(1) atoms to form SnO6 octahedra that share corners with six equivalent Fe(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to four equivalent Sr(1), one Fe(1), and one Sn(1) atom to form a mixture of distorted corner, face, and edge-sharing OSr4FeSn octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
