The compound described by Sr2CrOsO6 crystallizes in the trigonal R-3 space group. Sr(1) is bonded to twelve equivalent O(1) 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 Cr(1)O6 octahedra, and faces with four equivalent Os(1)O6 octahedra. Cr(1) is bonded to six equivalent O(1) atoms to form CrO6 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 are 14°. Os(1) is bonded to six equivalent O(1) atoms to form OsO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 14°. O(1) is bonded in a 6-coordinate geometry to four equivalent Sr(1), one Cr(1), and one Os(1) atom. is represented by the CIF file [CIF]
