Abstract

Recent advances in the synthesis of 3d/4f Single-Molecule Magnets (SMMs) have revealed the effective role of incorporating diamagnetic Co^III or Zn^II ions to enhance the magnetic properties of Ln^III ions. This concept highlights notable examples of Co^III/Ln^III and Zn^II/Ln^III SMMs documented in the recent literature, illustrating how the selection of various peripheral and/or bridging ligands can modulate the magnetic anisotropy of 4f metal ions, thereby increasing their energy barriers.

Keywords: 3d/4f SMMs; ab initio calculations; diamagnetic 3d metal ions; magnetic anisotropy; mulliken charges.
