- Abstract
A dichlorido‐bridged dinuclear dysprosium(III) single‐molecule magnet [Dy2L2(μ‐Cl)2(thf)2] has been made by using a diamine‐bis(phenolate) ligand, H2L. Magnetic studies show an energy barrier for magnetisation reversal (Ueff) around 1000 K. An exchange‐biasing effect is clearly seen in magnetic hysteresis with steps up to 3 K. Ab initio calculations exclude the possibility of a pure dipolar origin of this effect leading to the conclusion that super‐exchange through the chloride bridging ligands is important.
