K1-xLaxCa2-xNb3O10, a layered perovskite series with variable interlayer cation density, and LaCaNb3O10, a novel layered perovskite oxide with no interlayer cations
Description
A series of layered perovskite oxides of the formula K1-xLaxCa2-xNb3O10 for 0 < x ≤ 1.0 have been prepared. All the members are isostructural, possessing the structure of KCa2Nb3O10. The interlayer potassium ions in the new series can be ion-exchanged with protons to give H1-xLaxCa2-xNb3O10. The latter readily forms intercalation compounds of the formula (CnH2n+1NH3)1-xLaxCa2-xNb3O10, just as the parent solid acid HCa2Nb3O10. The end member LaCaNb3O10 containing no interlayer cations is a nove layered perovskite oxide, being a n = 3 member of the series An-1BnX3n+1. 16 refs., 5 figs., 5 tabs
