Binuclear Dy single-molecule magnetic material and preparation method thereof

The invention provides a binuclear Dy single-molecule magnetic material and a preparation method thereof and relates to a single-molecule magnetic material and a preparation method thereof, aiming atsolving the problems of an existing single-molecule magnetic material that the structure is not stable, a preparation method is complicated and the yield is low. An expression formula of the binuclearDy single-molecule magnetic material is [Dy2(PAN)2(OAc)4(H2O)2]; a structural formula is as follows: the formula is shown in the description. The method comprises the following steps: 1, preparing amixed solvent; 2, mixing dysprosium acetate, triethylamine and 1-(2-pyridine-azo)-2-naphthol and filtering to obtain filtrate; 3, dropwise adding ethyl ether into the filtrate and standing to obtain the Dy single-molecule magnetic material. The binuclear Dy single-molecule magnetic material can be obtained by the method. 种双核Dy单分子磁性材料及其制备方法，它涉及种单分子磁性材料及其制备方法。本发明的目的是要解决现有单分子磁性材料的结构不稳定，制备方法繁琐和产率低的问题。种双核Dy单分子磁性材料的表达式为[Dy(PAN)(O
