Sr2CoHfO6 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 Hf(1)O6 octahedra, and faces with four equivalent Co(1)O6 octahedra. Hf(1) is bonded to six equivalent O(1) atoms to form HfO6 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 Hf(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to four equivalent Sr(1), one Hf(1), and one Co(1) atom.
