The compound described by MgMn3TeO8 is beta indium sulfide-derived structured and crystallizes in the monoclinic Cm space group. Mg(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form MgO4 tetrahedra that share corners with three equivalent Mn(2)O6 octahedra, corners with three equivalent Te(1)O6 octahedra, and corners with six equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 54-64°. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form MnO6 octahedra that share corners with three equivalent Mg(1)O4 tetrahedra, edges with two equivalent Mn(1)O6 octahedra, edges with two equivalent Mn(2)O6 octahedra, and edges with two equivalent Te(1)O6 octahedra. In the second Mn site, Mn(2) is bonded to one O(1), one O(6), two equivalent O(2), and two equivalent O(4) atoms to form MnO6 octahedra that share corners with three equivalent Mg(1)O4 tetrahedra, edges with two equivalent Te(1)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. Te(1) is bonded to one O(3), one O(5), two equivalent O(2), and two equivalent O(4) atoms to form TeO6 octahedra that share corners with three equivalent Mg(1)O4 tetrahedra, edges with two equivalent Mn(2)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), one Mn(2), and two equivalent Mn(1) atoms to form a mixture of edge and corner-sharing OMgMn3 tetrahedra. In the second O site, O(2) is bonded to one Mg(1), one Mn(1), one Mn(2), and one Te(1) atom to form distorted OMgMn2Te trigonal pyramids that share  a cornercorner with one O(1)MgMn3 tetrahedra,  a cornercorner with one O(2)MgMn2Te trigonal pyramid,  an edgeedge with one O(1)MgMn3 tetrahedra, and  an edgeedge with one O(2)MgMn2Te trigonal pyramid. In the third O site, O(3) is bonded in a rectangular see-saw-like geometry to one Mg(1), two equivalent Mn(1), and one Te(1) atom. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one Mn(1), one Mn(2), and one Te(1) atom. In the fifth O site, O(5) is bonded in a distorted T-shaped geometry to two equivalent Mn(1) and one Te(1) atom. In the sixth O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one Mn(2) and two equivalent Mn(1) atoms. is represented by the CIF card [CIF]
