Metalloligands for designing single-molecule and single-chain magnets

Abstract

2-Hydroxy-N-{2-[2-hydroxyethyl)amino]ethyl}benzamide (L1H3) and 2-hydroxy-N-{2-[2-hydroxybutyl)amino]ethyl}benzamide (L2H3) ligands coordinate to copper ions to give anionic metalloligands, L1Cu and L2Cu, after deprotonation of their amide, alcohol and phenol functions. In presence of ancillary ligands as diketones, these metalloligands react with lanthanide salts to yield tetranuclear [Cu-Ln]2 complexes while in presence of lanthanide salts alone, L1Cu gives 1D chains of tetranuclear entities linked through the Ln ions. The micro-SQUID data evidence the SMM behavior of the tetranuclear Tb complexes and the SCM behavior of the Tb chain derivative.
