一种以2-甲基-5,7-二氯-8-羟基喹啉为配体的单核镝配合物及其制备方法和应用
摘要：
本发明公开了一种以2‑甲基‑5,7‑二氯‑8‑羟基喹啉为配体的单核镝配合物及其制备方法和应用。该配合物的化学式为：[Dy(L)4]·(H2O)(DMF)(HN(C2H5)3)，其中，L为2‑甲基‑5,7‑二氯‑8‑羟基喹啉脱去羟基氢原子，带一个单位负电荷；DMF为N,N‑二甲基甲酰胺；该配合物属于属于单斜晶系，P21/n空间群。该配合物是由Dy(NO3)3·6H2O和2‑甲基‑5,7‑二氯‑8‑羟基喹啉用混合溶剂溶解，调节所得溶液的pH＝6.5～7.8，所得混合液于加热条件下反应即得。本发明提供的配合物制备方法简单、成本低廉、重复性好，在低温下表现为场诱导的慢弛豫磁行为，可用于制备磁性材料。
摘要（英）：

The invention discloses a mononuclear dysprosium complex using 2-methyl-5,7-dichloro-8-hydroxyquinoline as ligand and a preparation method and application thereof. The chemical formula of the complex is [Dy(L)4].(H2O)(DMF)(HN(C2H5)3), wherein L represents 2-methyl-5,7-dichloro-8-hydroxyquinoline without hydroxyl hydrogen atoms and provided with a unit of negative charges, DMF is N,N-dimethylformamide, and the complex belongs to a P21/n space group of a monoclinic crystal system. The complex is obtained by dissolving Dy(NO3)3.6H2O and the 2-methyl-5,7-dichloro-8-hydroxyquinoline with mixed solvents, regulating the pH of the obtained solution to be 6.5 to 7. 8 and making the mixed solution react under the heating conditions. The preparation method of the complex is simple, cheap and good in repeatability, shows field induced slow relaxation magnetic behavior at low temperature and can be used for preparing magnetic materials.
