'All three-in-one': ferromagnetic interactions, single-molecule magnetism and magnetocaloric properties in a new family of [Cu4Ln] (Ln^III = Gd, Tb, Dy) clusters

A new family of isomorphous [CuLn] clusters (Ln = Gd, Tb, Dy) with a 'propeller'-like topology was obtained from the use of naphthalene-2,3-diol in Cu/Ln chemistry; all complexes are ferromagnetically-coupled and display either magnetocaloric properties or SMM behavior depending on the central Ln ion.
