Abstract

New derivatives of layered perovskite compounds with H₃O ⁺ ions, H⁺ ions and water molecules in the interlayer, H_xNa_1-xLaTiO₄·yH₂O, were successfully synthesized by an ion-exchange/intercalation reaction with dilute HCl solution, using an n=1 member of Ruddlesden-Popper phase, NaLaTiO ₄. Powder X-ray diffraction revealed that the layered structure changed from space group P4/nmm with a=3.776(1) and c=13.028(5)Å to I4/mmm with a=3.7533(3) and c=28.103(4)Å after the ion-exchange/intercalation reaction at pH 5. The change of space group indicates that the perovskite layers are transformed from staggered to an eclipsed configuration through the ion-exchange/intercalation reaction. Thermogravimetric analysis and high-temperature powder X-ray diffraction suggested the existence of the secondary hydrated phase by dehydrating H_xNa_1-xLaTiO ₄·yH₂O at 100°C.
