Deciphering the origin of giant magnetic anisotropy and fast quantum tunnelling in Rhenium(IV) single-molecule magnets

Abstract

Rhenium(IV) complexes are magnetically anisotropic although the origin of this anisotropy is poorly explored compared to 3dtransition metals and lanthanides. Here, the authors computationally examine the effects of ligand donor ability and structural distortion on magnetic anisotropy for a series of rhenium(IV) complexes.
