The structure described by Cu2O3 is Hausmannite-like structured and crystallizes in the cubic Ia-3 space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to six equivalent O(1) atoms to form a mixture of corner and edge-sharing CuO6 octahedra. The corner-sharing octahedral tilt angles are 48°. In the second Cu site, Cu(2) is bonded to six equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing CuO6 octahedra. The corner-sharing octahedral tilt angles range from 48-61°. O(1) is bonded in a distorted rectangular see-saw-like geometry to one Cu(1) and three equivalent Cu(2) atoms. is represented by the CIF file [CIF]
