Abstract
The linear trinuclear complex cation [Fe3(DpyF)4]2+ was prepared as [Fe3(DpyF)4](BF4)2·2CH3CN. With large Fe–Fe distances of 2.78 Å, this complex demonstrates intramolecular ferromagnetic coupling between the anisotropic FeII centers (J/kB = +20.9(5) K) giving an ST = 6 ground state and exhibits single-molecule magnet properties.
