Dodecanuclear 3d/4f-metal clusters with a 'Star of David' topology: Single-molecule magnetism and magnetocaloric properties

摘要

A family of interwoven molecular inorganic knots, shaped like the 'Star of David', was prepared by the employment of naphthalene-2,3-diol in 3d/4f-metal cluster chemistry; the isoskeletal dodecanuclear compounds exhibit slow relaxation of the magnetization and magnetocaloric properties, depending on the metal ion.
