The crystal structure described by MgFeAuO2 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a 3-coordinate geometry to three equivalent Au(1) and three equivalent O(2) atoms. Fe(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. Au(1) is bonded in a 4-coordinate geometry to three equivalent Mg(1) and one O(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Fe(1) and one Au(1) atom to form corner-sharing OFe3Au tetrahedra. In the second O site, O(2) is bonded in a 6-coordinate geometry to three equivalent Mg(1) and three equivalent Fe(1) atoms. is represented by the CIF file [CIF]
