POLYNUCLEAR TRANSITION METAL COMPLEXES: DEVELOPMENT OF SYNTHETIC STRATEGIES, REACTIVITY AND APPLICATIONS IN MAGNETIC AND CATALYTIC MATERIALS

Abstract: 

Polynuclear transition metal complexes (clusters) attract the intense interest of the chemical community due to their relevance in many interdisciplinary scientific fields. The presence of metal ions gives rise to properties such as magnetic and catalytic, and enables clusters to function as molecular materials.

The aims of this proposal are:

  • Development of novel synthetic strategies for the synthesis of high spin molecules and single-molecule magnets (SMMs).
  • Study of their reactivity at the molecular and supramolecular level.
  • Structural and magnetic characterization of the clusters and their reactivity products.
  • Evaluation of their catalytic properties in hydrocarbon oxidation with eco-friendly oxidants.

The proposal is organized in the following eight workpackages:

  1. Synthesis, reactivity and physicochemical characterization of metal clusters including the development of new synthetic strategies.
  2. Assembly of clusters in 1D, 2D and 3D coordination polymers, by means of new bridging organic ligands and new metallo-ligands.
  3. Structural characterization (x-ray crystallography) of the clusters and polymers.
  4. Variable temperature/field dc and ac magnetic studies, and development of magnetostructural correlations.
  5. Preparation of immobilized and encapsulated clusters in mesoporous materials prior to their catalytic evaluation.
  6. Catalytic studies of the clusters and their immobilized and encapsulated derivatives within mesoporous materials.
  7. Publication of results (journals/national/international conferences).
  8. Coordination/management.

The expected results include the preparation of new homo- and heterometallic high-spin clusters and SMMs as magnetic and catalytic materials. The isolated clusters, including those with interesting magnetic properties, such as the SMMs, will be further used for the synthesis of cluster-based coordination polymers (supramolecular reactivity of clusters) to afford single-chain and molecule-based magnets.
