摘要：

MLaNb2O7 (M = K, Na, Li, H) compounds were synthesized by a solid state reaction for M = K and by ion exchange for M = Na, Li and H, respectively, and their crystal structures were analysed by a Rietveld method. In the structures for all the compounds, the main framework is built up of a double layer of perovskite units (LaNb2O7) and an alkali ion or proton is located at the sites between the layers. Ionic conduction attributed to the interlayer ion was observed above 200-degrees-C for all the compounds.
