Research Group on Coordination Chemistry

Description

The group specialises in the design, programmed synthesis and characterisation of mono-and polynuclear coordination compounds with pre-established crystal structures and spin topologies. In particular, the group's preparative strategy is based on the conception and use of the complex as a ligand, i.e. a stable compound that acts as a ligand against solvated metal ions or complexes preformed with the unsaturated coordination sphere. This precursor species may already carry one or several functions (chirality, photo- or redox-active, paramagnetic, etc.), bearing in mind the multifunctionality of the desired final species. This work is eminently basic in nature, i.e. fundamental, and the main results obtained include the following:

Design, materialisation and characterisation of the first examples of one-dimensional bimetallic compounds with ferromagnetic coupling and magnet behaviour (magnet chains).
First examples of chiral magnet chains.
First examples of rational design and materialisation of photomagnetic or redox-magnetic switches with oxamate-complexes.
Obtaining and characteristion of the first molecular-based proton magnet.
Programmed preparation and characterisation of the first example of bimetallic oxalate-complex (tri-and tetranuclear) with molecular magnet properties.
Preparation of porous coordination polymers with gas and solvent absorbing properties.
Design of chemical switches based on pH-based oxamate-complexes that facilitate the emulsion of an organic phase in water with a view to accelerating catalytic processes in homogeneous phase.
Design and characterisation of hexa-coordinated mononuclear compounds of Co(II) and Mn(III) that constitute novel examples of Single Ion Magnets (SIMs).
Design and materialisation of the first examples of photoactive and magnetic molecular precursors based on oxamate-complexes.
Preparation and characterisation of multiferroic coordination compounds: coexistence of ferromagnetism, ferroelectricity and non-linear optics (true multifunctional compounds designed to order).
Modelling and interpretation of magnetic properties through the Spin Hamiltonian and theoretical calculations of the DFT and MonteCarlo type, both Quantum and Classical.
