Materials Data on Cu2PbO2 by Materials Project
PbCu2O2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Cu–O bond lengths are 1.86 Å. In the second Cu1+ site, Cu1+ is bonded in a linear geometry to two equivalent O2- atoms. Both Cu–O bond lengths are 1.86 Å. Pb2+ is bonded in a rectangular see-saw-like geometry to four equivalent O2- atoms. There are two shorter (2.31 Å) and two longer (2.52 Å) Pb–O bond lengths. O2- is bonded to two Cu1+ and two equivalent Pb2+ atoms to form a mixture of distorted corner and edge-sharing OCu2Pb2 tetrahedra.
