A Dodecanuclear Dysprosium Wheel Assembled by Six Vertex-Sharing Dy₃ Triangles Exhibiting Slow Magnetic Relaxation

Abstract

Reactions of lanthanide(III) (Ln(III)) perchlorate (Ln = Dy and Ho) and a polydentate Schiff base resulted in the unprecedented assembly of novel Ln(12) wheels containing six vertex-sharing Ln(3) triangles. The Dy(12) derivative represents the largest lanthanide wheel based on the peculiar Dy(3) triangles showing slow magnetic relaxation.
