Single‐Molecule Magnets A new Zn‐Dy‐Zn single‐molecule magnet has been prepared, in which the Dy III ion, that exhibits a DyO 8 coordination sphere, is placed in an axial ligand field formed by two pairs of negatively charged phenoxide oxygen atoms in positions opposite to the Dy III ion and four neutral aldehyde oxygen atoms in the equatorial plane. This disposition leads to a strong easy‐axis anisotropy of the ground state and to a high thermal energy barrier U eff =140 K. For more information, see the Full Paper by J. M. Seco, E. Ruiz, E. Colacio and co‐workers on page 14262 ff.
