• Ferrocene–phenol resin was synthesized from 1-ferrocenylethanol, phenol, and formaldehyde in the presence of an ammonia catalyst. The resin structure was elucidated by chemical and infrared analyses and then confirmed by micro Vickers hardness measurements. To liberate iron atoms from ferrocene skeletons, the resin was pyrolyzed <I>in vacuo</I> at 400 °C. The properties of the iron dispersed in a glasslike carbon matrix were investigated by magnetic susceptibility measurements, ESR, and Mössbauer spectroscopy. The iron atoms coagulated into ferromagnetic iron particles in the glasslike carbon matrix. This coagulation is discussed in connection with the resin structure.
