MgCrSbO4 crystallizes in the orthorhombic Imm2 space group. Mg(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form MgO6 octahedra that share corners with two equivalent Sb(1)O6 octahedra, corners with four equivalent Mg(1)O6 octahedra, edges with four equivalent Cr(1)O6 octahedra, and edges with four equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-13°. Cr(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form CrO6 octahedra that share corners with four equivalent Cr(1)O6 octahedra, edges with four equivalent Mg(1)O6 octahedra, and edges with four equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 3-9°. Sb(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form SbO6 octahedra that share corners with two equivalent Mg(1)O6 octahedra, corners with four equivalent Sb(1)O6 octahedra, edges with four equivalent Mg(1)O6 octahedra, and edges with four equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-19°. There are four inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Mg(1), one Cr(1), and two equivalent Sb(1) atoms to form a mixture of corner and edge-sharing OMg2CrSb2 square pyramids. In the second O site, O(2) is bonded in a distorted square co-planar geometry to one Mg(1), two equivalent Cr(1), and one Sb(1) atom. In the third O site, O(3) is bonded to two equivalent Mg(1), one Cr(1), and two equivalent Sb(1) atoms to form a mixture of corner and edge-sharing OMg2CrSb2 square pyramids. In the fourth O site, O(4) is bonded in a square co-planar geometry to one Mg(1), two equivalent Cr(1), and one Sb(1) atom.
