The crystal structure described by PbCu2O2 crystallizes in the monoclinic C2/c space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a linear geometry to two equivalent O(1) atoms. In the second Cu site, Cu(2) is bonded in a linear geometry to two equivalent O(1) atoms. Pb(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) atoms. O(1) is bonded to one Cu(1), one Cu(2), and two equivalent Pb(1) atoms to form a mixture of distorted corner and edge-sharing OCu2Pb2 tetrahedra. is represented by the CIF file [CIF]
