The crystal structure described by Sr2GaSbO6 crystallizes in the tetragonal I4/m space group. Sr(1) is bonded to four equivalent O(2) and eight 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 Ga(1)O6 octahedra, and faces with four equivalent Sb(1)O6 octahedra. Ga(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form GaO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-19°. Sb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form SbO6 octahedra that share corners with six equivalent Ga(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-19°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to four equivalent Sr(1), one Ga(1), and one Sb(1) atom. In the second O site, O(2) is bonded to four equivalent Sr(1), one Ga(1), and one Sb(1) atom to form a mixture of distorted edge and corner-sharing OSr4GaSb octahedra. The corner-sharing octahedral tilt angles range from 0-1°. is represented by the Crystallographic Information File (CIF) [CIF]

Sr(1) is bonded to four equivalent O(2) and eight 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 Ga(1)O6 octahedra, and faces with four equivalent Sb(1)O6 octahedra. Ga(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form GaO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra and faces with eight equivalent Sr(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-19°.
