The compound described by NaMg(Cu3O4)2 crystallizes in the cubic Fm-3m space group. Na(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. Mg(1) is bonded to twelve equivalent Cu(1) atoms to form MgCu12 cuboctahedra that share corners with twelve equivalent Mg(1)Cu12 cuboctahedra and edges with twenty-four equivalent O(1)NaCu3 tetrahedra. Cu(1) is bonded in a square co-planar geometry to two equivalent Mg(1) and four equivalent O(1) atoms. O(1) is bonded to one Na(1) and three equivalent Cu(1) atoms to form distorted ONaCu3 tetrahedra that share corners with ten equivalent O(1)NaCu3 tetrahedra, edges with three equivalent Mg(1)Cu12 cuboctahedra, and edges with three equivalent O(1)NaCu3 tetrahedra. is represented by the CIF file [CIF]
