Body-wing swapping in butterfly {Fe~(III) _2Ln ~(III) _2} coordination clusters with triethylene glycol as ligand

摘要

The first use of triethylene glycol (H_2teg) in Fe/Ln chemistry affords two series of tetranuclear {Fe~(III))2Ln ~(III) _2} 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.
