Enhancing the ferromagnetic coupling in extended phloroglucinol complexes by increasing the metal SOMO–ligand overlap: synthesis and characterization of a trinuclear CoII3 triplesalophen complex
The better overlap of the SOMO with the central π-system in the CoII3 than in the CuII3 complex enhances the spin-polarization and thus the ferromagnetic coupling.

ligands, still has a strong but smaller contribution in the trinucleartriplesalophencomplexes. The magnetic properties demonstrate weak intramolecular ferromagneticinteractions mediated by the triplesalophen ligands in the trinuclear CuII3 complexes, which are experimentally difficult to determine due to intermolecular antiferromagnetic interactions of the same order of magnitude.

origins of cooperativity are not always well understood. Here, two trimetallic Al complexes and their monometallic analogues are synthesised, characterised and employed as catalysts in cyclic ester ring-opening polymerisation, providing spectroscopic and kinetic insights into the reasons behind the performance enhancements observed.
