Dy(iii)-Carboxylate chain containing quasi-D5h sites exhibits enhanced energy barrier for magnetization reversal

Abstract

A slight modification of the coordinating solvent molecule induced a change in the local symmetry at one of the metal sites of a Dy(III)-carboxylate chain complex from quasi-D_5h (hepta-coordinated) to C_2v (octa-coordinated). This afforded an effective energy barrier for magnetization reversal, which was significantly changed from 403.6 K (diluted) to about 7.5 K.
