An Old Reaction with New Results: The Unexpected Formation of a Rare Earth Metal Cluster Containing Six Europium Atoms

Abstract Employing a standard protocol for the preparation of a trisbenzoylacetonato europium(III) complex with 4‐bromo benzoylacetone 2 as ligand, a new europium species was synthesized and characterized. The X‐ray crystal structure analysis revealed a new europium cluster consisting of six europiumcentres.
