Abstract
A new family of hexanuclear ferric-lanthanide [Fe(III)(4)Ln(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.
摘要
一种新的六核铁-镧系[Fe(III)(4)Ln(III)(2)(Htea)(4)(Piv)(6)(N(3))(4)]簇合物被报道，其中 Ln(III) = Er(1)和 Lu(2)。1 和 2 的变温固态磁化率研究表明，组成 Fe(III)离子之间存在铁磁（1）或竞争的反铁磁和铁磁交换相互作用（2）。
