The compound described by CuO crystallizes in the monoclinic C2/c 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 edge and corner-sharing OCu4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
