Abstract

A new low symmetry octanuclear cyano-based {Fe^III₄Ni^II₄} single-molecule magnet (SMM) is described. This SMM exhibits the highest energy barrier (Δ/k_B ≈ 33 K) for magnetization reversal seen for any first-row cyanide-based complex. The importance of anisotropy axes alignment and their impact on SMM properties are illustrated when cubic {Fe^III₄Ni^II₄} boxes are compared to octanuclear complexes of lower overall symmetry.
