The structure described by NaCuO crystallizes in the tetragonal I4/mmm space group. Na(1) is bonded in a see-saw-like geometry to four equivalent O(1) atoms. Cu(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to four equivalent Na(1) and two equivalent Cu(1) atoms to form a mixture of corner and edge-sharing ONa4Cu2 octahedra. The corner-sharing octahedral tilt angles range from 1-14°. is represented by the Crystallographic Information File (CIF) [CIF]
