摘要：

A new family of hexanuclear ferric-lanthanide [Fe(4)(III)Ln(2)(III)(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.
