Two triple-decker dinuclear sandwich dysprosium complexes, which are represented as Dy[Pc(OCH)][Cor(FPh)] (1) and Dy[Pc(OCH)][Cor(ClPh)] (2), were synthesized and characterized by spectroscopic and electrochemical methods in nonaqueous media. Their electronic structures were also investigated on the basis of TD-DFT calculations. The sandwich triple-decker nature with the molecular conformation of [Pc(OCH)]Dy[Cor(FPh)]Dy[Pc(OCH)] for compound 1 was unambiguously revealed by single-crystal X-ray diffraction analysis and showed each dyprosium ion to be octacoordinated by the isoindole and pyrrole nitrogen atoms of an outer phthalocyanine ring and the central corrole ring, respectively. In addition, the magnetic properties of both compounds have also been characterized for exploring the functionalities of these types of triple-decker complexes.
合成了两种三层双核夹心镝配合物，分别表示为Dy[Pc(OCH)][Cor(FPh)] (1)和Dy[Pc(OCH)][Cor(ClPh)] (2)，并在非水介质中通过光谱和电化学方法对其进行了表征。还基于TD-DFT计算研究了它们的电子结构。通过单晶X射线衍射分析明确揭示了化合物1的[Pc(OCH)]Dy[Cor(FPh)]Dy[Pc(OCH)]分子构象的夹心三层结构，表明每个镝离子分别由外部酞菁环和中心咕啉环的异吲哚和吡咯氮原子八配位。此外，还对这两种化合物的磁性进行了表征，以探索这类三层配合物的功能。
