The pressure-assisted photopolymerization in the fullerene complex {Cd(dedtc)2}2·C60 (fullerene complex with cadmium diethyldithiocarbamate) observed in the pressure region between 2.24 and 5.99 GPa was studied in detail. After a phase transition near ∼ 2 GPa, the Raman spectra exhibit time-dependent changes under prolonged laser illumination regarding the appearance of new peaks in the frequency region of the Ag(2) mode of the C60 monomer. These peaks are related to the fullerene oligomers with a different number of sp3-like coordinated carbon atoms per molecular cage. The polymer content increases with the laser power density and exposure time, while for a fixed laser power, its saturated value is independent of pressure. Outside the pressure range 2.24 – 5.99 GPa, photopolymerization is suppressed.
