From Serendipitous Assembly to Controlled Synthesis of 3d–4f Single-Molecule Magnets

Learning from serendipitous assembly, we have prepared a new family of designed 3d–4f Mn6Ln complexes. The dynamics of relaxation of the magnetization via alternating-current magnetic susceptibility for the new Mn6Ln complexes 1 (Ln = La), 2 (Ln = Tb), and 4 (Ln = Dy) have been studied down to 0.2 K.
