Chemical tuning of the magnetic relaxation in dysprosium(iii) mononuclear complexes.
A dysprosium(iii) complex, exhibiting slow relaxation of magnetization, was prepared. Crystallographic studies showed a perturbation of local symmetry upon deprotonation of the ligand, with concomitant faster relaxation of magnetization. This was attributed to a large shift in the direction of the main magnetic axis, as indicated by ab initio calculations.
