Mn-Ln heterometallic monomolecular magnets, because the system contains two metal ions with different properties, exhibit different coordination characteristics. For the same ligand, there is often competitive coordination, and the reaction is often more complex than that of homonuclear monomolecular magnets. Thus, compared with homonuclear monomolecular magnets, Mn-Ln heterometallic monomolecular magnets have relatively few reports.
