The material structure described by MgMn4(CuO4)2 crystallizes in the monoclinic C2/m space group. Mg(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MgO6 octahedra that share corners with four equivalent Mn(1)O6 octahedra, corners with six equivalent Mn(2)O6 octahedra, edges with two equivalent Mn(3)O6 octahedra, and faces with two equivalent Mn(1)O6 octahedra.

In the third Mn site, Mn(3) is bonded to two equivalent O(3) and four equivalent O(1) atoms to form MnO6 octahedra that share corners with four equivalent Mn(1)O6 octahedra, edges with two equivalent Mg(1)O6 octahedra, edges with two equivalent Mn(2)O6 octahedra, and faces with two equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles are 39°. Cu(1) is bonded in a distorted square co-planar geometry to two equivalent O(2) and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Mg(1), one Mn(2), one Mn(3), and two equivalent Mn(1) atoms.
