The crystal structure described by MgMn2(CoO4)2 is beta indium sulfide-derived structured and crystallizes in the orthorhombic Imm2 space group. Mg(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form MgO4 tetrahedra that share corners with six equivalent Mn(1)O6 octahedra and corners with six equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 59-62°. Mn(1) is bonded to one O(1), one O(4), two equivalent O(2), and two equivalent O(3) atoms to form MnO6 octahedra that share corners with three equivalent Mg(1)O4 tetrahedra, edges with two equivalent Mn(1)O6 octahedra, and edges with four equivalent Co(1)O6 octahedra. Co(1) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms to form CoO6 octahedra that share corners with three equivalent Mg(1)O4 tetrahedra, edges with two equivalent Co(1)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), one Mn(1), and two equivalent Co(1) atoms to form distorted OMgMnCo2 tetrahedra that share  a cornercorner with one O(1)MgMnCo2 tetrahedra, corners with two equivalent O(2)MgMn2Co tetrahedra,  an edgeedge with one O(1)MgMnCo2 tetrahedra, and edges with two equivalent O(2)MgMn2Co tetrahedra. In the second O site, O(2) is bonded to one Mg(1), two equivalent Mn(1), and one Co(1) atom to form distorted OMgMn2Co tetrahedra that share  a cornercorner with one O(2)MgMn2Co tetrahedra, corners with two equivalent O(1)MgMnCo2 tetrahedra,  an edgeedge with one O(2)MgMn2Co tetrahedra, and edges with two equivalent O(1)MgMnCo2 tetrahedra. In the third O site, O(3) is bonded in a distorted T-shaped geometry to two equivalent Mn(1) and one Co(1) atom. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one Mn(1) and two equivalent Co(1) atoms. is represented by the CIF card [CIF]
