n-Alkylammonium-HxBiNb2O7 intercalation compounds were synthesized by the reaction of perovskite-related layered oxide HBiNb2O7·nH2O with n-alkylamines. HBiNb2O7·nH2O was not completely converted to the intercalation compounds except for the methylammonium-intercalate. The intercalating capability of HBiNb2O7·nH2O was much lower than those of other previously reported perovskite-related layered niobates such as HCa2Nb3O10. The poor reactivity was assumed to be related to unusual irreversible dehydrating behavior of HBiNb2O7·nH2O. On the other hand, the interlayer structure was similar to that of the n-alkylammonium-HxCa2Nb3O10 intercalates in contrast to the difference in the reactivity.
