Single-Molecule Magnets (SMMs) are coordination complexes of paramagnetic metal ions that display slow relaxation of magnetization below their blocking temperature that are currently intensively researched for applications that include memory storage devices. The introduction of chirality into this family of molecules creates opportunities for new properties such as magnetochiral dichroism (MChD), as well as applications in the field of multiferroics. We have thus recently initiated a new program of research aimed at the development of small, potentially chiral chelating ligands for the discovery of metal clusters with unprecedented structural motifs and novel magnetic and/or electronic properties. Our first target ligand, α-methyl-2-pyridine-methanol or mpmH (1), previously unexplored in the field of cluster chemistry, possesses similar coordination features to the well-studied 2-(hydroxymethyl)pyridine or hmpH system (2), but subtly differs in its steric and electronic nature. The synthesis, structural and magnetic properties of 3d/4f polynuclear clusters prepared from the mpmH chelate (1) will be presented.
