The main target of the research of the Molecular Magnetism Group is the syntheses of polynuclear 3d or 4f systems based in the Coordination Chemistry with relevant magnetic properties. This research field implies synthetic work (ligands design, reactivity and characterization) as well the study of the magnetic properties of the new systems, mainly related to magneto-structural correlations, molecular-based magnets or single molecule magnets (SMM). Current interest is focused on enantiomerically pure chiral complexes.
