摘要

用一般公式报道了三种异质金属{FeIII4LnIII2}配位团簇;[FeIII4LnIII2(μ4-O)2(Hedte)2(piv)6(NO3)2]∙2MeCN∙2CH2Cl2 {Ln = Tb(1)， Ho(2)和Er(3)，其中Hedte = N,N,N,N '——四基-(2-羟乙基)乙二胺;此外 = 特戊酸}。这些团簇是由FeCl2·4H2O、戊酸、Ln(NO3)3·6H2O和H4edte在MeCN/CH2Cl2中反应得到的。x射线测量显示，1-3个星团呈现“蝴蝶”核心形状。固态直流磁化率测量表明，1中存在铁磁相互作用，而2和3中存在反铁磁相互作用。

Synthesis, structures, and magnetic properties of Fe4-Ln2 (Ln = Tb, Ho, and Er) clusters with N, N, N′, N′-tetrakis-(2-hydroxyethyl)ethylenediamine

Three isostructural heterometallic {Fe^III₄Ln^III₂} coordination clusters are reported with genernal formula; [Fe^III₄Ln^III₂(μ₄-O)₂(Hedte)₂(piv)₆(NO₃)₂]∙2MeCN∙2CH₂Cl₂ {Ln = Tb(1), Ho(2) and Er(3), where Hedte = N,N,N,N′--tetrakis-(2-hydroxyethyl)ethylenediamine; piv = pivalic acid}. These clusters are obtained by reacting the FeCl₂·4H₂O, pivalic acid, Ln(NO₃)₃·6H₂O, and H₄edte in MeCN/CH₂Cl₂. X-ray measurements revealed that 1–3 clusters exhibit a “butterfly” core shape. Solid-state dc-magnetic susceptibility measurement indicates the ferromagnetic interactions in 1 while 2 and 3 demonstrates dominated antiferromagnetic interactions.

期刊介绍： Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews. Topics covered include: • chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies; • synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs); • reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models; • applications of inorganic compounds, metallodrugs and molecule-based materials. Papers composed primarily of structural reports will typically not be considered for publication.
