| Abstract: | Full chemical control of magnetic anisotropy in hexairon(III ) rings can be achieved by varying the size of the guest alkali metal ion. Dramatically different anisotropies characterize the LiI and NaI complexes of [Fe6(OMe)12(L)6] (L=1,3-propanedione derivatives; a schematic representation of the LiI complex is shown), as revealed by high-field torque magnetometry—Iron: (g), oxygen: ○, carbon: ○, Li+: ⊕. |
