This invention belongs to the field of
rare earth-transition complex preparation technology, and discloses a pentanuclear
rare earth-transition heterometallic complex, its preparation method, and its applications. The preparation method provided by this invention is as follows: Dy(CF3SO3)3, NiCl2·6H2O, and ligand H2L (1,2-di(1-methyl-1H-benzo[d]imidazol-2-yl)ethane-1,2-
diol) are mixed and dissolved in CH3OH and H2O in a certain proportion. Then, Et3N and NaN3 are added. The
mixed solution is stirred at 80°C, allowed to stand and evaporate, and the reaction is completed to obtain blue blocky crystals. This pentanuclear
rare earth-transition heterometallic complex has a bow-tie-shaped metallic framework structure and can be applied to the preparation of molecular magnetic materials and
molecular memory materials.
