The first exploration of coordination chemistry using a methyl substituted o-vanillin based ligand: an example starting with Dy4/Zn2Dy2 systems displaying slow relaxation of magnetization

Two butterfly-shaped Dy 4 and Zn 2 Dy 2 complexes displaying slow relaxation of magnetization have been synthesized from a new methyl substituted o -vanillin based ligand, enlarging the scope for finding better SMMs.
