Sr2OsGaO6 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 Os(1)O6 octahedra, and faces with four equivalent Ga(1)O6 octahedra. Os(1) is bonded to six equivalent O(1) atoms to form OsO6 octahedra that share corners with six equivalent Ga(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Ga(1) is bonded to six equivalent O(1) atoms to form GaO6 octahedra that share corners with six equivalent Os(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded to four equivalent Sr(1), one Os(1), and one Ga(1) atom to form a mixture of distorted corner, edge, and face-sharing OSr4GaOs octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
