The compound described by MgCu2O4 crystallizes in the tetragonal I4_1/amd space group. Mg(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded in a distorted trigonal planar geometry to one Mg(1) and two equivalent Cu(1) atoms. is represented by the CIF file [CIF]
