摘要

根据 Dy(hfac)3-2H2O、Cu(hfac)3-2H2O、Cu(hfac)3-2H2O 和 Dy(hfac)4-H2O 一锅法，得到了一种不连续的 3d-4f 加合物，其式为 {[Cu(hfac)(Nit-PhCH2-PyN)]+[Dy(hfac)4]-} （hfac=六氟乙酰丙酮，Nit-PhCH2-PyN=2-[4-[双(2-吡啶甲基)胺]-甲苯基]-4,4,5、在 Dy(hfac)3-2H2O、Cu(hfac)2-2H2O 和三叉螯合配体 Nit-PhCH2-PyN 的一锅法基础上，制备出了 5-四甲基咪唑啉-1-氧-3-氧化物。有趣的是，3d-4f 复合物中存在一个离散的[Dy(hfac)4]-阴离子和作为反离子的[Cu(hfac)(Nit-PhCH2-PyN)]+。此外，磁性研究表明，磁场诱导的慢磁弛豫来自于[Dy(hfac)4]-阴离子，涉及具有 D4d 对称性的八配位 DyIII 离子。

Tridentate chelate ligand-based Dy-Cu adduct: synthesis, structure and magnetic properties

One discrete 3d-4f adduct with formula {[Cu(hfac)(Nit-PhCH₂-PyN)]⁺[Dy(hfac)₄]^–} (hfac=hexafluoroacetylacetonate, Nit-PhCH₂-PyN=2-[4-[bi(2-pyridylmethyl)amine]-tolyl]-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide) has been afforded on the basis of a one-pot process of Dy(hfac)₃·2H₂O, Cu(hfac)₂·2H₂O and a tridentate chelate ligand Nit-PhCH₂-PyN. Interestingly, one discrete [Dy(hfac)₄]^– anion and [Cu(hfac)(Nit-PhCH₂-PyN)]⁺ serving as the counter-ion are present in the 3d-4f complex. In addition, magnetic studies have shown field-induced slow magnetic relaxation is derived from the [Dy(hfac)₄]^– anion, involving the eight-coordinated Dy^III ion with D_4d symmetry.

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.
