Body-wing swapping in butterfly {FeIII2LnIII2} coordination clusters with triethylene glycol as ligand

Abstract

The first use of triethylene glycol (H₂teg) in Fe/Ln chemistry affords two series of tetranuclear {Fe^III₂Ln^III₂} coordination clusters possessing defect-dicubane cores. A change in the synthetic procedure results in a different arrangement of the relative positions of the 3d and 4f elements offering a means to steer the structural and electronic features within a 3d–4f system.
