Hard versus soft: zero-field dinuclear Dy(III) oxygen bridged SMM and theoretical predictions of the sulfur and selenium analogues

Author affiliations

Abstract

Two dinuclear lanthanide complexes (Gd and Dy) were prepared and characterized by X-ray, magnetic and computational methods. The Dy analogue shows SMM behavior with an energy barrier of 98.4 K in the absence of an applied dc field. Theoretical calculations were performed on model complexes which support the hypothesis that the energy barrier will increase if the soft-donor atoms S and Se are used in lieu of an O donor.
