Materials Data on CuPb2Cl3O2 by Materials Project
CuCl3(PbO)2 crystallizes in the tetragonal I4_1/acd space group. The structure is one-dimensional and consists of eight PbO clusters and four CuCl3 ribbons oriented in the (0, 0, 1) direction. In each PbO cluster, Pb3+ is bonded in a 3-coordinate geometry to three equivalent O2- atoms. There are one shorter (2.28 Å) and two longer (2.29 Å) Pb–O bond lengths. O2- is bonded in a distorted trigonal non-coplanar geometry to three equivalent Pb3+ atoms. In each CuCl3 ribbon, Cu1+ is bonded to four Cl1- atoms to form corner-sharing CuCl4 tetrahedra. There are two shorter (2.28 Å) and two longer (2.43 Å) Cu–Cl bond lengths. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Cu1+ atom. In the second Cl1- site, Cl1- is bonded in a distorted bent 120 degrees geometry to two equivalent Cu1+ atoms.
