Abstract

original image

Macrocyclic single-molecule magnet: The dynamic behavior of the tetranuclear zinc(II)–dysprosium(III) complex of the hexaimine [3+3] macrocycle (LPr)6− under an external DC field (1500 Oe) indicates that it is a single-molecule magnet (SMM). It is the first to contain a single lanthanide ion (in orange, see graphic) coordinated inside the cavity of a single macrocyclic ligand and thus represents a new class of SMM.
