The reaction of potassium 2,5-bis{N-(2,6-diisopropylphenyl)iminomethyl} pyrrolyl, [(DIP2pyr)K], with the anhydrous lanthanide diiodides resulted in the heteroleptic complexes [(DIP2pyr)LnI(THF) 3] (Ln = Sm, Eu, Yb). All complexes are monomeric in the solid state, which is remarkable, since samarium and europium complexes tend to form dimeric complexes bridged by iodine ions. The (DIP2pyr)- ligands are coordinated almost symmetrically in a κ3 N, N′, N″ mode to the metal center in the samarium and europium compounds. In contrast, for the ytterbium complex an asymmetric coordination mode was observed.
