CuCl4O2 crystallizes in the orthorhombic Fddd space group. Cu(1) is bonded in a 4-coordinate geometry to four equivalent O(1) and four equivalent Cl(1) atoms. O(1) is bonded in a distorted square co-planar geometry to two equivalent Cu(1) and two equivalent Cl(1) atoms. Cl(1) is bonded in a 3-coordinate geometry to one Cu(1), one O(1), and one Cl(1) atom.
