Abstract:Integrating controllable spin states into single‐molecule magnets (SMMs) enables precise manipulation of magnetic interactions at a molecular level, but remains a synthetic challenge. Herein, we developed a 3d‐4f metallacrown (MC) magnet [DyNi5(quinha)5(Clsal)2(py)8](ClO4)∙4H2O (H2quinha = quinaldichydroxamic acid, HClsal = 5‐chlorosalicylaldehyde) wherein a square planar NiII is stabilized by chemical stacking. Thioacetal modification was employed via post‐synthetic ligand substitutions and yielded [DyNi5(qui… Show more
