NaMgCu2O3 crystallizes in the orthorhombic Cmmm space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a linear geometry to two equivalent Mg(1) atoms. In the second Na site, Na(1) is bonded in a linear geometry to two equivalent Mg(1) atoms. Mg(1) is bonded in a square co-planar geometry to two equivalent Na(1), two equivalent O(1), and two equivalent O(2) atoms. Cu(1) is bonded in a square co-planar geometry to one O(2) and three equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a square co-planar geometry to one Mg(1) and three equivalent Cu(1) atoms. In the second O site, O(2) is bonded in a square co-planar geometry to two equivalent Mg(1) and two equivalent Cu(1) atoms.
