通过配体邻苯二胺缩邻香兰素(H_2L)与Dy(NO_3)_3·6H_2O反应,合成了类Salen稀土配合物[Dy_5L_4(NO_3)_4(CH_3O)_2]·NO_3·3CH_2Cl_2(1),X-射线单晶衍射分析确定了该配合物的晶体结构为独特的五核四夹层的结构。磁性分析研究表明该配合物具有慢弛豫磁性。
The complex of Salen rare earth [Dy_5L_4 (NO_3) _4 (CH_3O) _2] · NO_3 · 3CH_2Cl_2 (1) has been synthesized by the reaction of the ligand o-phenylenediamine condensed o-vanillin with Dy (NO_3) _3 · 6H_2O. X-ray single crystal diffraction analysis confirmed the crystal structure of the complex as a unique five-core four sandwich structure. Magnetic analysis shows that the complex has slow relaxivity.
