Slow magnetic relaxation in a {Co^IICoIII2} complex containing a high magnetic anisotropy trigonal bipyramidal Co^II centre

Abstract

We report a trinuclear mixed-valence {CoIICoIII2} complex, where the CoII centre adopts a trigonal bipyramidal geometry, leading to a large, easy-plane magnetic anisotropy and field-induced slow magnetic relaxation with a Raman-like relaxation process.
