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.
