Mononuclear lanthanide( iii )-based complexes with β-thiooxoketone and β-diketone as ligands: effects of soft (S) vs. hard (O) donor substitution on magnetic and luminescent properties

Mononuclear lanthanide complexes: donor substitution from O (hard donor) to S (soft donor) modulates the Dy( iii ) local environment leading to changes in electronic structure and properties.
