La6BaYCu8O20 is a new three-dimensional oxygen deficient perovskite related to the well-known three-dimensional material La4BaCu5O13. The inclusion of a small rare earth results in an extension of the layerlike areas within the three-dimensional network. The same structure is also found for La6BaDyCu8O20. The structure can be doped with Sr for La, or Ca for the small lanthanide. No superconductivity is observed down to 0.3 K. La4BaCu5O13 and the new compound form the first two members of a new three-dimensional homologous series La4+2nBaLnnCu5+3nO13+7n through the addition of “123” type structural units.
