Abstract

Four low-coordinate SIMs have been studied to probe their relaxation dynamics using ab initio calculations. Our calculations reveal that both the symmetry and the equatorial ligand field play a key role in controlling the barrier heights in three-coordinate [Ln^III(NSiMe₃)₃] complexes (Ln = Dy/Er). This study reveals an unprecedented blockade of magnetization up to three excited states for the Er(iii) complex. 2014
