The compound described by Cu2O3 crystallizes in the triclinic P1 space group. There are four inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(3), one O(6), and two equivalent O(2) atoms. In the second Cu site, Cu(2) is bonded in a distorted rectangular see-saw-like geometry to one O(2), one O(4), one O(5), and two equivalent O(3) atoms. In the third Cu site, Cu(3) is bonded in a distorted rectangular see-saw-like geometry to one O(3), one O(4), one O(6), and two equivalent O(5) atoms. In the fourth Cu site, Cu(4) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(2), one O(5), and two equivalent O(6) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded in a water-like geometry to one Cu(1) and one Cu(4) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Cu(2), one Cu(4), and two equivalent Cu(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Cu(1), one Cu(3), and two equivalent Cu(2) atoms.
