Breaking Symmetry Relaxes Structural and Magnetic Restraints, Suppressing QTM in Enantiopure Butterfly Fe₂ Dy₂ SMMs*.

ABSTRACT: The {Fe₂ Dy₂ } butterfly systems can show single molecule magnet (SMM) behaviour, the nature of which depends on details of the electronic structure, as previously demonstrated for the [Fe₂ Dy₂ (μ₃ -OH)₂ (Me-teaH)₂ (O₂ CPh)₆ ] compound, where the [N,N-bis-(2-hydroxyethyl)-amino]-2-propanol (Me-teaH₃ ) ligand is usually used in its racemic form. Here, we describe the consequences for the SMM properties by using enantiopure versions of this ligand and present the first homochiral 3d/4 f SMM, which could only be obtained for the S enantiomer of the ligand for [Fe₂ Dy₂ (μ₃ -OH)₂ (Me-teaH)₂ (O₂ CPh)₆ ] since th
