The structure described by Sr2CoOsO6 crystallizes in the tetragonal I4/m space group. Sr(1) is bonded to four equivalent O(1) and eight equivalent O(2) atoms to form distorted SrO12 cuboctahedra that share corners with twelve equivalent Sr(1)O12 cuboctahedra, faces with six equivalent Sr(1)O12 cuboctahedra, faces with four equivalent Os(1)O6 octahedra, and faces with four equivalent Co(1)O6 octahedra. Os(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form OsO6 octahedra that share corners with six equivalent Co(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-15°. 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 Os(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-15°. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent Sr(1), one Os(1), and one Co(1) atom to form a mixture of distorted corner and edge-sharing OSr4CoOs octahedra. The corner-sharing octahedral tilt angles range from 0-4°. In the second O site, O(2) is bonded in a 6-coordinate geometry to four equivalent Sr(1), one Os(1), and one Co(1) atom. is represented by the CIF file [CIF]
