摘要

三个二维杂质基-3d-4f 网络，其式为{[Ln(hfac)3]2[M(hfac)2](NIT-3Py-5-Pyoe)2}n（MII = CoII 和 LnIII = Gd 1，Dy 2；MII = CuII 和 LnIII = Dy 3；NIT-3Py-5-Pyoe = (2-(5-(4-吡啶酮)-3-吡啶基)-4,4,5,5-四甲基咪唑啉-1-氧代-3-氧化物))是利用一种含有混合 N 和 O 供体位点的新型多叉硝基顺磁配体成功构建的。在这些二维结构中，顺磁配体作为三叉连接体，通过一个氨基羟基和一个吡啶酮单元与两个 LnIII 离子结合，并通过吡啶环与一个 MII 离子结合。1-3 的磁性行为主要受铁磁基-Ln 相互作用的支配。

Unique 3d–4f Heterometallic Networks Based on a Nitronyl Nitroxide Radical Functionalized with Additional N and O Donors

Three 2D heterospin radical-3d–4f networks with the formula {[Ln(hfac)₃]₂[M(hfac)₂](NIT-3Py-5-Pyoe)₂}_n (M^II = Co^II and Ln^III = Gd 1, Dy 2; M^II = Cu^II and Ln^III = Dy 3; NIT-3Py-5-Pyoe = (2-(5-(4-pyridinone)-3-pyridyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide)) have been successfully constructed using a novel multidentate nitronyl nitroxide paramagnetic ligand containing mixed N- and O-donor sites. In these 2D structures, the paramagnetic ligand acts as a tridentate linker to bind two Ln^III ions by means of one aminoxyl group and one pyridinone unit and one M^II ion through the pyridine ring. The magnetic behaviors of 1–3 are governed by predominant ferromagnetic radical–Ln interactions.

期刊介绍： The aim of Crystal Growth & Design is to stimulate crossfertilization of knowledge among scientists and engineers working in the fields of crystal growth, crystal engineering, and the industrial application of crystalline materials. Crystal Growth & Design publishes theoretical and experimental studies of the physical, chemical, and biological phenomena and processes related to the design, growth, and application of crystalline materials. Synergistic approaches originating from different disciplines and technologies and integrating the fields of crystal growth, crystal engineering, intermolecular interactions, and industrial application are encouraged.
