‘All three-in-one’: ferromagnetic interactions, single-molecule magnetism and magnetocaloric properties in a new family of [Cu(4)Ln] (Ln(III) = Gd, Tb, Dy) clusters.

A new family of isomorphous [Cu(4)Ln] 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.
