The compound described by Sr2FeCoO6 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal R-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 Co(1)O6 octahedra. Fe(1) is bonded to six equivalent O(1) atoms to form FeO6 octahedra that share corners with six equivalent Co(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Co(1) is bonded to six equivalent O(1) atoms to form CoO6 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 Co(1) atom to form a mixture of distorted edge, corner, and face-sharing OSr4FeCo octahedra. The corner-sharing octahedral tilt angles range from 0-60°. is represented by the CIF file [CIF]
