Sr2YCoO6 is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal I4/mmm space group. Sr(1) is bonded to four equivalent O(1) and eight equivalent O(2) 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 Y(1)O6 octahedra, and faces with four equivalent Co(1)O6 octahedra. Y(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form YO6 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 two equivalent O(1) and four equivalent O(2) atoms to form CoO6 octahedra that share corners with six equivalent Y(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to four equivalent Sr(1), one Y(1), and one Co(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to four equivalent Sr(1), one Y(1), and one Co(1) atom.
