The adsorption of the cluster Rh6(CO)16 on the surface of partially hydroxylated magnesia leads mainly to the dianionic cluster [Mg]2+ [Rh6(CO)15]2-, which has been characterized by in situ infrared spectroscopy, extraction by surface anion exchange, and analysis of gases evolved. It is suggested that Rh6(CO)16 undergoes on the surface a nucleophilic attack at coordinated CO, leading to a [HRh6(CO)15]- intermediate, which would undergo a deprotonation by the surface OH- groups of magnesia.
