Synthesis, spectra and magnetism of the charge-transfer complex formed by fullerene with decamethylferrocene
A charge-transfer complex of fullerene (C-60) with decamethyl/errocene (Fc*) was prepared. The charge-transfer properties were investigated by infrared and electronic spectroscopy and by electron paramagnetic resonance. A complicated reaction was observed. Variable temperature EPR spectral study in the solid state showed that the g-value shifts with peak-width change. A relaxation with degradation process of this charge-transfer complex was proposed. Magnetic studies conducted by SQUID magnetometer showed that the magnetic behavior of these charge-transfer complexes may be described as a superposition of paramagnetic and ferromagnetic components. The coercive forces and residual magnetizations of these complexes measured at low temperature are described herewith.
