The material described by NaMgCu2O3 crystallizes in the monoclinic Pm space group. Na(1) is bonded in a 4-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Mg(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a distorted T-shaped geometry to one O(1), one O(2), and one O(3) atom. In the second Cu site, Cu(2) is bonded in a distorted T-shaped geometry to one O(1), one O(2), and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to two equivalent Na(1), two equivalent Mg(1), one Cu(1), and one Cu(2) atom. In the second O site, O(2) is bonded to two equivalent Na(1), two equivalent Mg(1), one Cu(1), and one Cu(2) atom to form distorted edge-sharing ONa2Mg2Cu2 octahedra. In the third O site, O(3) is bonded in a 6-coordinate geometry to two equivalent Na(1), two equivalent Mg(1), one Cu(1), and one Cu(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
