Abstract

The new hexaferrocene complex 1 has been synthesized and characterized by X-ray diffraction. Its magnetization data were fitted to a detailed theoretical model that considers nonequivalent exchange parameters between Fe ions to yield the magnetic exchange coupling values of J1/kB = -31.5 K and J2/kB = -25.8 K. Moreover, the cyclic voltammogram of complex 1 confirmed its redox activity associated with the presence of ferrocene units, with very small or negligible electronic interactions between them.
