由于含有两个三齿结合单元的配体L与Sm(III)、Eu(III)、Tb(III)和Dy(III)离子配位，形成了含有两个配位数为9的离子的新的双核结构。根据它们的溶液光谱和微量分析数据对它们的结构进行了归属，并用X-射线单晶衍射法对Eu(III)配合物2进行了确证。双核配合物2的结构分析表明存在两个Eu中心[Eu(1)和Eu(2)]和四个配体L。每个Eu离子由9个配位原子配位，具有典型的Eu-N和Eu-O距离。(C)Wiley-VCH Verlag GmbH&Co.KGaA，69451，德国温海姆。
As a result of coordination of the ligand L, containing two tridentate binding units, to samarium(III), europium(III), terbium(III), and dysprosium(III) ions, new dinuclear architectures containing two ions with coordination number 9 were formed. The structures of the complexes have been assigned on the basis of their solution spectroscopic and microanalytical data, and confirmed by X-ray crystallography in the case of the europium(III) complex 2. The structural analysis of the dinuclear complex 2 showed the presence of two europium centers [Eu(1) and Eu(2)] and four ligands L. Each europium ion is coordinated by 9 donor atoms with typical Eu-N and Eu-O distances. (C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.
