Abstract

A magneto-structural study of two salicylamidoxime-based {Mn₆} single-molecule magnets revealed that their anisotropy energy barriers, which can reach the current record for d-transition metal complexes, are strongly dependent upon the precise arrangement of ligands and the solvation state.
