Benzoxazole-Based Heterometallic Dodecanuclear Complex [Dy^III₄Cu^II₈] with Single-Molecule-Magnet Behavior

Abstract

Three Cu-Ln (Ln = Dy, Gd, Y) dodecanuclear clusters assembled by a novel ligand of the benzoxazole type are reported. The dysprosium cluster exhibits a frequency dependence of the alternating-current susceptibility and hysteresis loop at low temperature, indicating single-molecule-magnet behavior.
