Abstract

A new family of hexanuclear ferric-lanthanide [FeIII4LnIII2(Htea)4(Piv)6(N3)4] clusters, where LnIII = Er(1) and Lu(2) is reported. Variable temperature solid-state magnetic susceptibility studies of 1 and 2 reveal the presence of ferromagnetic (1) or competing anti- and ferromagnetic exchange interactions (2) between the constituent FeIII ions.
