Magnetic frustration in a hexaazatrinaphthylene-bridged trimetallic dysprosium single-molecule magnet

Abstract

The synthesis, structure and magnetic properties of the HAN-bridged tri-dysprosium complex [{(thd)3Dy}3HAN] (1) are described. The complex is an SMM that shows two relaxation processes owing to the presence of two geometrically distinct Dy3+ sites in 1. Ab initio calculations reveal that the magnetic ground state of 1 is characterized by magnetic frustration.
