摘要

A new family of hexanuclear ferric-lanthanide [Fe~Ⅲ_4Ln~Ⅲ_2(Htea)_4-(Piv)_6(N_3)_4] clusters, where Ln~Ⅲ = 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 Fe~Ⅲ ions.
