The structure of a complex two-dimensional supercell observed by high-resolution electron microscopy in a layered bismuthate has been deduced from structural chemistry principles. It is proposed that this superstructure should form the basis for a new type of homologous series of related structures. An n = 5 member of the series, with composition Bi18Ti9Fe14O66, has been synthesized and shown to have regions with the same two-dimensional superstructure.
