The crystal structure described by MgMn2(WO4)2 is beta indium sulfide-derived structured and crystallizes in the monoclinic P2 space group. Mg(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted MgO6 octahedra that share corners with four equivalent W(2)O6 octahedra, edges with two equivalent Mn(1)O6 octahedra, edges with two equivalent Mn(2)O6 octahedra, and faces with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 28-50°. There are two inequivalent W sites. In the first W site, W(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted WO6 octahedra that share corners with four equivalent Mn(1)O6 octahedra, corners with four equivalent Mn(2)O6 octahedra, edges with two equivalent W(2)O6 octahedra, and faces with two equivalent Mg(1)O6 octahedra.

The corner-sharing octahedral tilt angles range from 42-56°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one W(2), one Mn(1), and one Mn(2) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Mg(1), one W(1), one Mn(1), and one Mn(2) atom.
