Abstract

A pair of enantiopure Fe^III₄ SMMs with axial symmetry was synthesized and characterized by magnetization and high-frequency electron paramagnetic resonance methods. The results reveal that the axial symmetry of the structure is broken by the interaction of Fe^III₄ with the disordered solvent molecules.
