Abstract

Abstract : The importance of ligand field and origin of SMM behaviour of an asymmetric [Er III (HL)2 (NO3 )3 ] complex investigated in detail which is strongly supported by theoretical calculations. Dipolar interaction in1 significantly reduced upon dilution which increases the barrier height to 51.5 K. 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 in1 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.
