Abstract
The synthesis and characterization of a carboxy-substituted alkylpyridinium cation with inorganic counterions is reported. Structural evidence points to the formation of a layered structure with mutual recognition of cations through strong O-(HO)-O-... bonding when halides X- (X = Cl, Br) are chosen. Variation of the anionic component to complex metal ions of [MX4](2-) type affords a different layer motif with weaker cation-anion O-(HX)-X-...-M interactions and interdigitation of functionalized alkyl chains.File in questo prodotto:
