Abstract
SummaryChloroxiphite, Pb3CuO2(OH)2Cl2, is monoclinic, space groupP21/m, witha= 10·458,b= 5·750,c= 6·693 Å, β = 97·79°,Z= 2. The structure has been refined by the method of least squares from three-dimensional Mo-Kα intensity data to a conventionalRvalue of 0·115. The structure consists of sheets of composition [Pb3CuO2(OH)2]2−, in themselves made up of the layer sequence Pb-(O, OH, Cu)-Pb, lying parallel to (01). The structure contains eight-fold PbO4Cl4and seven-fold PbO5Cl2polyhedra common in other oxychlorides, Pb6clusters and copper atoms in square planar, Cu(OH)4, coordination.
