Magnetic refrigeration and slow magnetic relaxation in tetranuclear lanthanide cages (Ln = Gd, Dy) with in situ ligand transformation

Abstract

Three tetranuclear lanthanide cages featuring either hemicubane (<bold>1</bold> and <bold>2</bold>) or distorted hemicubane (<bold>3</bold>) like cores are reported. Magnetic studies reveal significant magnetic entropy changes for complex <bold>1</bold> and a slow relaxation of magnetisation for <bold>3</bold>.
