Abstract

A new layered copper oxide structure type is reported based on the ordered interleaving of AlO₄, CoO₄ or GaO₄ tetrahedra between the apices of copper oxide pyramids, and an (Nd, Ce)₂O₂ fluorite layer between the bases of the pyramids. Despite the structural similarities to the recently reported Sr₂(Y, Ca)GaCu₂O₇ and Sr₂(Nd, Ce)₂NbCu₂O₁₀ superconducting structure types, we have not been able to find conditions which produce superconductivity in the present materials.
