Abstract

Reaction of tris(2-aminoethyl)amine coordinated to lanthanum(III) and gadolinium(III) with salicylaldehyde afforded Schiff-base complexes of tris[2-(salicylideneamino)ethyl] amine. In this reaction, a lanthanum(III) complex, which was supposed to be a reaction intermediate, was also obtained and characterized by X-ray crystallography. However, such a reaction intermediate of gadolinium(III) complex was not isolated under similar conditions. This difference was applied to the mutual separation of lanthanum(III) and gadolinium(III).
