Sr2ReGaO6 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 Re(1)O6 octahedra, and faces with four equivalent Ga(1)O6 octahedra. Re(1) is bonded to six equivalent O(1) atoms to form ReO6 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 Re(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 Re(1), and one Ga(1) atom to form a mixture of distorted edge, face, and corner-sharing OSr4GaRe octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
