Abstract

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.
