Research Abstract |
We developed novel rare-earth and transition-metal heterometallic complexes, which show single-molecule magnet behavior, and elucidated their magnetic couplings. As for trinuclear complexes [DyMDy] (M = Pd, Cu, Ni), single-molecule magnet performance was enhanced with increasing the spin quantum numbers of M ions. The [DyNiDy]-type complex with the methylimidazole ligands at the axial positions showed high performance compared to the complex having the pyridine ligands, which is due to a difference of coordination geometries around the Dy ions. In addition, we demonstrated the chemical trends of magnetic coupling between rare-earth and transition-metal spins for [LnCu], [LnV], [CuLnCu], [Ln4Cu], and [Ln2Cu2]n.
