Abstract: Conclusions 1. IR spectroscopy was used to study the interaction of Co2(CO)8 with SiO2, the surface of which was modified with mono- and polydentate ligands (Si-O)x-(OC2H5)4−x−n [(CH2)3PR2]n (R=Ph, Cy; n=1–3). It has been demonstrated that the Co2(CO)8 is fixed on phosphine-containing SiO2 with the formation of predominately monophosphine-substituted dicobalt carbonyl complexes on the surface of the support, which are transformed to the corresponding diphosphine-substituted complexes in the absence or in the presence of low pressures of CO. 2. It has been found that covalently fixed cobalt complexes are decarbonylated irreversibly when heated in vacuum. The preservation of a linkage between the decarbonylated CO particles and the phosphine ligands on the SiO2 surface prevents the formation of a metallic phase.
