The structure described by Sr2MgCrSbO6 crystallizes in the monoclinic C2/m space group. Sr(1) is bonded in a 3-coordinate geometry to three equivalent O(1) and six equivalent O(2) atoms. Mg(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. Cr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CrO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 27-31°. Sb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SbO6 octahedra that share corners with six equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 27-31°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to three equivalent Sr(1), one Cr(1), and one Sb(1) atom. In the second O site, O(2) is bonded in a 6-coordinate geometry to three equivalent Sr(1), one Mg(1), one Cr(1), and one Sb(1) atom. is represented by the CIF card [CIF]
