A linear metal-metal bonded tri-iron single-molecule magnet

The linear trinuclear complex cation [Fe-3(DpyF)(4)](2+) was prepared as [Fe-3(DpyF)(4)](BF4)(2)center dot 2CH(3)CN. With large Fe-Fe distances of 2.78 angstrom, this complex demonstrates intramolecular ferromagnetic coupling between the anisotropic Fe-II centers (J/k(B) = +20.9(5) K) giving an S-T = 6 ground state and exhibits single-molecule magnet properties.
