The compound described by CuO crystallizes in the orthorhombic Cccm space group. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to four equivalent Cu(1) atoms to form a mixture of corner and edge-sharing OCu4 tetrahedra. is represented by the CIF card [CIF]
