The crystal structure described by MgCoMnO4 crystallizes in the monoclinic P2/m space group. Mg(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MgO6 octahedra that share corners with six equivalent Co(1)O6 octahedra, edges with two equivalent Mg(1)O6 octahedra, edges with two equivalent Co(1)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 11-13°. Mn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MnO6 octahedra that share edges with two equivalent Mn(1)O6 octahedra, edges with four equivalent Mg(1)O6 octahedra, and edges with four equivalent Co(1)O6 octahedra. Co(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CoO6 octahedra that share corners with six equivalent Mg(1)O6 octahedra, edges with two equivalent Mg(1)O6 octahedra, edges with two equivalent Co(1)O6 octahedra, and edges with four equivalent Mn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 11-13°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to one Mg(1), two equivalent Mn(1), and one Co(1) atom. In the second O site, O(2) is bonded to two equivalent Mg(1), one Mn(1), and two equivalent Co(1) atoms to form a mixture of edge and corner-sharing OMg2MnCo2 square pyramids. is represented by the CIF file [CIF]
