Abstract

The crystal structure and basic properties of a new layered copper oxychloride, Pb3Sr3Cu3O8+δCl, are described. The new structure type is related to that of Pb2Sr2RECu3O8+δ, with the RE (rare-earth) layer replaced by an (Sr, Pb)-Cl-(Sr, Pb) layer. A wide range of oxygen stoichiometry is observed. The new compound has the planes of CuO5 pyramids required for high-Tc superconductivity, but we have been unable to introduce enough (positive or negative) charge to drive it superconducting.
