The crystal structure described by Sr2CrOsO6 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal R-3m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to three equivalent O(2) and nine equivalent O(1) atoms to form SrO12 cuboctahedra that share corners with six equivalent Sr(1)O12 cuboctahedra, corners with six equivalent Sr(2)O12 cuboctahedra, faces with three equivalent Sr(1)O12 cuboctahedra, faces with three equivalent Sr(2)O12 cuboctahedra,  a faceface with one Os(1)O6 octahedra, faces with three equivalent Os(2)O6 octahedra, and faces with four equivalent Cr(1)O6 octahedra. In the second Sr site, Sr(2) is bonded to three equivalent O(1) and nine equivalent O(2) atoms to form SrO12 cuboctahedra that share corners with six equivalent Sr(1)O12 cuboctahedra, corners with six equivalent Sr(2)O12 cuboctahedra, faces with three equivalent Sr(1)O12 cuboctahedra, faces with three equivalent Sr(2)O12 cuboctahedra,  a faceface with one Os(2)O6 octahedra, faces with three equivalent Os(1)O6 octahedra, and faces with four equivalent Cr(1)O6 octahedra. Cr(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form CrO6 octahedra that share corners with three equivalent Os(1)O6 octahedra, corners with three equivalent Os(2)O6 octahedra, faces with four equivalent Sr(1)O12 cuboctahedra, and faces with four equivalent Sr(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 1°. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded to six equivalent O(2) atoms to form OsO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra, faces with two equivalent Sr(1)O12 cuboctahedra, and faces with six equivalent Sr(2)O12 cuboctahedra. The corner-sharing octahedral tilt angles are 1°.

The corner-sharing octahedral tilt angles are 1°. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Sr(2), three equivalent Sr(1), one Cr(1), and one Os(2) atom to form a mixture of distorted face, corner, and edge-sharing OSr4CrOs octahedra. The corner-sharing octahedral tilt angles range from 0-61°. In the second O site, O(2) is bonded to one Sr(1), three equivalent Sr(2), one Cr(1), and one Os(1) atom to form a mixture of distorted face, corner, and edge-sharing OSr4CrOs octahedra.
