摘要
n-ALkylammonium-HxBiNb2O7 intercalation compounds were synthesized by the reaction of perovskite-related layered oxide HBiNb2O7 . nH(2)O with n-alkylamines. HBiNb2O7 . nH(2)O was not completely converted to the intercalation compounds except for the methylammonium-intercalate. The intercalating capability of HBiNb2O7 . nH(2)O was much lower than those of other previously reported perovskite-related layered niobates such as HCa2O7Nb3O10. The poor reactivity was assumed to be related to unusual irreversible dehydrating behavior of HBiNb2O7 . nH(2)O. 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.
