Stannole dianions for axially coordinated lanthanide single-molecule magnets

Nature Chemistry, Published online: 21 April 2026; doi:10.1038/s41557-026-02149-y To control the magnetic anisotropy of single-molecule magnets, precise engineering of the ligands is crucial. Now, homoleptic bis(stannolediide) complexes are synthesized with trivalent terbium, as well as trivalent and divalent dysprosium, expanding the series of axially coordinated lanthanide single-molecule magnets.
