Enantiopure sandwich-type nonanuclear Ln~(III)_3Mn ~(III)_6 clusters

摘要

Three enantiopure isostructural sandwich-type clusters, Ln ~(III)_3Mn~(III)_6 (Ln = Dy (1), Tb (2) and Gd (3)) have been synthesized through reactions of a chiral Schiff-base ligand ((S,E)-4-(2-hydroxybenzylideneamino)-2-hydroxybutanoic acid, H_3L) with manganese and lanthanide ions, showing intramolecular antiferromagnetic interaction.
