Here, we describe the consequences for the SMM properties by using enantiopure versions of this ligand and present the first homochiral 3d\/4\u2009f SMM, which could only be obtained for the <jats:italic>S<\/jats:italic> enantiomer of the ligand for <jats:bold>[Fe<jats:sub>2<\/jats:sub>Dy<jats:sub>2<\/jats:sub>(\u03bc<jats:sub>3<\/jats:sub>\u2010OH)<jats:sub>2<\/jats:sub>(Me\u2010teaH)<jats:sub>2<\/jats:sub>(O<jats:sub>2<\/jats:sub>CPh)<jats:sub>6<\/jats:sub>]<\/jats:bold> since the <jats:italic>R<\/jats:italic> enantiomer underwent significant racemisation.

Remarkably, the enantiopure versions show enhanced slow relaxation of magnetisation. The use of the enantiomerically pure ligand suppresses QTM, leading to the conclusion that use of enantiopure ligands is a \u201cgamechanger\u201d by breaking the cluster symmetry and altering the intimate details of the coordination cluster's molecular
