| Abstract: | IR spectra of propylene adsorbed in CoO-MgO and CoO-MgO-MoO3 solid solutions show that a surface  -complex with Co2+ ions is formed, strongly bonded in the former case and weakly in the latter. Thus, introduction of Mo strongly modifies the catalytic properties of Co2+ active centers. In the presence of oxygen, allylic species, aldehyde and carboxylate complexes appear.
