Materials Data on CuPb2(ClO)2 by Materials Project

Abstract

CuPb2(OCl)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Cu2+ is bonded in a distorted square co-planar geometry to four equivalent O2- and two equivalent Cl1- atoms. All Cu–O bond lengths are 2.01 Å. Both Cu–Cl bond lengths are 2.94 Å. Pb2+ is bonded in a 9-coordinate geometry to four equivalent O2- and five equivalent Cl1- atoms. All Pb–O bond lengths are 2.66 Å. There are four shorter (3.08 Å) and one longer (3.46 Å) Pb–Cl bond lengths. O2- is bonded in a distorted linear geometry to two equivalent Cu2+ and four equivalent Pb2+ atoms. Cl1- is bonded in a 6-coordinate geometry to one Cu2+ and five equivalent Pb2+ atoms.
