The crystal structure described by MgCrSbO4 crystallizes in the orthorhombic Imm2 space group. Mg(1) is bonded to one O(1), two equivalent O(2), and two equivalent O(4) atoms to form MgO5 trigonal bipyramids that share  a cornercorner with one Cr(1)O6 octahedra, corners with two equivalent Sb(1)O6 octahedra, corners with four equivalent Mg(1)O5 trigonal bipyramids, edges with two equivalent Sb(1)O6 octahedra, and edges with four equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-72°. 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,  a cornercorner with one Mg(1)O5 trigonal bipyramid, edges with four equivalent Sb(1)O6 octahedra, and edges with four equivalent Mg(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 0-17°. Sb(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form distorted SbO6 octahedra that share corners with four equivalent Sb(1)O6 octahedra, corners with two equivalent Mg(1)O5 trigonal bipyramids, edges with four equivalent Cr(1)O6 octahedra, and edges with two equivalent Mg(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 6-38°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a square co-planar geometry to one Mg(1), one Cr(1), and two equivalent Sb(1) atoms. In the second O site, O(2) is bonded to two equivalent Mg(1), two equivalent Cr(1), and one Sb(1) atom to form a mixture of corner and edge-sharing OMg2Cr2Sb trigonal bipyramids. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Cr(1) and two equivalent Sb(1) atoms. In the fourth O site, O(4) is bonded to two equivalent Mg(1), two equivalent Cr(1), and one Sb(1) atom to form a mixture of distorted corner and edge-sharing OMg2Cr2Sb square pyramids. is represented by the CIF file [CIF]
