摘要：

A new series of layered perovskite oxides, K[Ca2(Ca,Sr)n-3Nb3Tin-3O3n+1], has been prepared by the incorporation of Ca(Sr)TiO3 perovskite slabs into KCa2Nb3O10. With an increase in n, there is a progressive increase in unit cell parameters. Potassium atoms in these compounds can be exchanged by protons and these protonated forms do not show a doubled c axis. Proton-exchanged forms of these layered perovskite oxides are solid acids and react with organic bases such as n-hexylamine, forming n-C6H13NH3[Ca2(Ca,Sr)n-3Nb3Tin-3O3n+1], resulting in large layer separations. © 1991.
