The material described by MgMnSbO4 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 distorted MgO5 trigonal bipyramids that share  a cornercorner with one Sb(1)O6 octahedra, corners with two equivalent Mn(1)O6 octahedra, corners with four equivalent Mg(1)O5 trigonal bipyramids, edges with two equivalent Mn(1)O6 octahedra, and edges with four equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-69°. Mn(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form MnO6 octahedra that share corners with four equivalent Mn(1)O6 octahedra, corners with two equivalent Mg(1)O5 trigonal bipyramids, edges with four equivalent Sb(1)O6 octahedra, and edges with two equivalent Mg(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 6-32°. Sb(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form SbO6 octahedra that share corners with four equivalent Sb(1)O6 octahedra,  a cornercorner with one Mg(1)O5 trigonal bipyramid, edges with four equivalent Mn(1)O6 octahedra, and edges with four equivalent Mg(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 2-15°. 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), two equivalent Mn(1), and one Sb(1) atom. In the second O site, O(2) is bonded to two equivalent Mg(1), one Mn(1), and two equivalent Sb(1) atoms to form a mixture of corner and edge-sharing OMg2MnSb2 trigonal bipyramids. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Mn(1) and one Sb(1) atom. In the fourth O site, O(4) is bonded to two equivalent Mg(1), one Mn(1), and two equivalent Sb(1) atoms to form a mixture of corner and edge-sharing OMg2MnSb2 square pyramids. is represented by the CIF file [CIF]
