The Magnetic Interactions and Molecular Magnetism research group is dedicated to the Chemistry of Coordination of polynuclear compounds, whether they are discrete aggregates or monodimensional, two-dimensional or three-dimensional species, making their synthesis, structural characterization and magnetic studies (measures of magnetic susceptibility , magnetization and paramagnetic resonance spectroscopy). At present, special attention is paid to the complexes built from enantiomerically pure chiral ligands that allows the direct synthesis of chiral coordination compounds that can be useful in the search of multifunctional systems in which optical or emissive properties could be combined with its magnetic response. The objectives of the research are: 1) to find magnetic-structural relationships based on the magnetic and structural data of the new complexes in order to expand the field of these relationships and to predict and synthesize new polynuclear species with predetermined magnetic properties; 2) to reach the formation of new molecular magnets (SIM or SMM), either from discrete species of high nuclearity through the use of ions with strong anisotropy (Mn (III) or lanthanides) that can give rise to the formation of complexes in a fundamental state of high spin and/or large anisotropy; 3) to study the effect of the enantiopure systems in supramolecular chirality; 4) study mixed valence manganese species that behave as models of bioinorganic processes.
