Intercalation of alkylamines into α-tin (IV) bis (hydrogenphosphate) [α-SnP] was investigated in aqueous and benzene solutions by chemical and XRD analyses. The interlayer distance of the intercalation compounds was proportional to the number of carbon atoms (nc) in alkylamines, in the wide range of nc 1 to 16. The alkylamines in α-SnP formed bilayer, where only three alkylamine molecules were bonded to every four P-OH groups present on the α-SnP layers. Their alkyl chains with a trans-trans conformation inclined roughly at 65° with respect to the α-SnP layer.
