INOR 187 |
| We address the problem of increasing magnetic anisotropy (D) in high-spin exchange-coupled clusters to afford species that display magnetic bistability at higher temperatures. Two related projects represent initial efforts to reduce cluster symmetry and manage spin in exchange-coupled clusters. The first project targets high-nuclearity complexes of paramagnetic transition metal ions bridged by 1,3,5-triethynylbenzene ligands. The rigid ligands impose ferromagnetic coupling between metal ions as well as a disk-like topology. In a related project, we aim to enforce linear geometries in exchange-coupled species by the covalent linking of Schiff base metal complexes prior to cluster formation. |
