Mesostructured composites of layered perovskites and cationic surfactants were synthesized. Layeredperovskite HCa2Nb3O10 and alkyltrimethylammonium (CnTMA) or alkylpridinium (CnPy) surfactantsformed lamellar-type composites. The interlayer spacings of the composites increased with increasing carbonnumber of alkyl group in the surfactants. The spacings were also affected by the Nb: surfactant ratio in thereacting solutions. From comparison between size of molecule and interlayer spacing, it is suggested thattwo types of composites formed, which contain C16Py+ ions with mono-or bilayer arrangements.
