The compound described by NaCuO2 crystallizes in the orthorhombic Cmcm space group. Na(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Cu(1) is bonded in a rectangular see-saw-like geometry to four equivalent O(1) atoms. O(1) is bonded to three equivalent Na(1) and two equivalent Cu(1) atoms to form a mixture of edge, corner, and face-sharing ONa3Cu2 trigonal bipyramids. is represented by the CIF card [CIF]
