Abstract

An asymmetric erbium(iii) Schiff base complex [Er(HL)₂(NO₃)₃] was synthesized which shows SMM behaviour with an Ueff of 5.2 K. Dipolar interaction in 1 significantly reduced upon dilution which increases the barrier height to 51.5 K. Ab initio calculations were performed to shed light on the mechanism of magnetization relaxation.
