Abstract Lanthanide ions (Ln 3+) are 'hard ' acids, in the Pearson sense. The majority of complexes isolated from aqueous ystems contain pure oxygen donors or mixed nitrogen-oxygen donor ligands (Moeller, 1972). Little is known about the interaction of organic ligands with Ln 3 § in clays. Bruque et al. (1982) and Mozas et aL (1982) have suggested the formation of ion dipole type coordination compounds of Ln 3+ with amines and ketones in montmorillonite. Clay properties uch as charge density or charge localization may affect, however, the intercalation mechanism of organic substances. The objective of this work was to study the interaction of Ln 3+ with several amides in vermiculite.
