The compound described by MgFe4(CoO4)2 is Aluminum carbonitride-derived structured and crystallizes in the orthorhombic Imm2 space group. Mg(1) is bonded to two equivalent O(1) and two equivalent O(4) atoms to form distorted MgO4 tetrahedra that share corners with six equivalent Fe(1)O6 octahedra, corners with two equivalent Co(2)O4 tetrahedra, and  an edgeedge with one Co(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 36-60°. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form FeO6 octahedra that share corners with three equivalent Mg(1)O4 tetrahedra, corners with three equivalent Co(1)O4 tetrahedra, corners with three equivalent Co(2)O4 tetrahedra, and edges with two equivalent Fe(1)O6 octahedra. In the second Fe site, Fe(2) is bonded in a 5-coordinate geometry to one O(2), two equivalent O(1), and two equivalent O(3) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(3) and two equivalent O(4) atoms to form distorted CoO4 tetrahedra that share corners with six equivalent Fe(1)O6 octahedra and  an edgeedge with one Mg(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 55-66°. In the second Co site, Co(2) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form CoO4 tetrahedra that share corners with six equivalent Fe(1)O6 octahedra and corners with two equivalent Mg(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 55-63°. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Mg(1), one Fe(1), two equivalent Fe(2), and one Co(2) atom to form distorted OMgFe3Co trigonal bipyramids that share corners with five equivalent O(3)Fe3Co tetrahedra,  a cornercorner with one O(1)MgFe3Co trigonal bipyramid, and  a faceface with one O(1)MgFe3Co trigonal bipyramid. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Fe(2), two equivalent Fe(1), and one Co(2) atom. In the third O site, O(3) is bonded to one Fe(1), two equivalent Fe(2), and one Co(1) atom to form OFe3Co tetrahedra that share  a cornercorner with one O(3)Fe3Co tetrahedra, corners with five equivalent O(1)MgFe3Co trigonal bipyramids, and  an edgeedge with one O(3)Fe3Co tetrahedra. In the fourth O site, O(4) is bonded in a distorted rectangular see-saw-like geometry to one Mg(1), two equivalent Fe(1), and one Co(1) atom. is represented by the CIF card [CIF]
