Abstract

original image

Designer-SMM: Ein ErIII-basierter Einzelmolekülmagnet (SMM) wurde synthetisiert, indem durch Einsatz eines Schiff-Basenliganden mit drei ZnII-Ionen die Ligandenfeldanisotropie um ein ErIII-Ion in einer äquatorialen Donoranordnung eingestellt wurde. Der resultierende ErIIIZnII3-Komplex (siehe Struktur; C grau, O rot, N blau) verhält sich als SMM mit einer Energiebarriere von 24.6(9) K für das Umschalten des molekularen magnetischen Moments.
