The structure described by NaMgCuO2 crystallizes in the triclinic P1 space group. Na(1) is bonded in a 4-coordinate geometry to one O(2) and three equivalent O(1) atoms. Mg(1) is bonded to one O(2) and three equivalent O(1) atoms to form corner-sharing MgO4 tetrahedra. Cu(1) is bonded in a 3-coordinate geometry to three equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Na(1) and three equivalent Mg(1) atoms to form distorted edge-sharing ONa3Mg3 octahedra. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Na(1), one Mg(1), and three equivalent Cu(1) atoms. is represented by the CIF file [CIF]
