Abstract

A new family of isomorphous [Cu₄Ln] clusters (Ln^III = Gd, Tb, Dy) with a ‘propeller’-like topology was obtained from the use of naphthalene-2,3-diol in Cu^II/Ln^III chemistry; all complexes are ferromagnetically-coupled and display either magnetocaloric properties or SMM behavior depending on the central Ln ion.
