The crystal structure described by NaCu2O3 crystallizes in the orthorhombic Pmmn space group. Na(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form distorted corner-sharing NaO4 tetrahedra. 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 distorted see-saw-like geometry to one Na(1) and three equivalent Cu(1) atoms. In the second O site, O(2) is bonded to two equivalent Na(1) and two equivalent Cu(1) atoms to form corner-sharing ONa2Cu2 tetrahedra. is represented by the CIF card [CIF]
