Organometallic compounds often react with metal oxide surfaces much as they react in solutions having properties (e.g., basicity) similar to those of the surfaces. The nature of the chemisorption may be simple, for example, resembling ion pairing, but it may instead lead to substantial restructuring of the adsorbate, e.g., when [Ir(CO){sub 2}(acac)] and CO are converted into [Ir{sub 6}(CO){sub 16}] on {gamma}-Al{sub 2}O{sub 3}. The authors now report on an even more complex chemisorption -- a corrosive chemisorption -- of an organometallic compound, [PtRh{sub 5}(CO){sub 15}]{sup {minus}}, whereby the adsorbate reacts with the adsorbent, MgO, incorporating Mg in the desorbed species. Corrosive chemisorption on metals is well-known, as exemplified by CO on supported Ru{sup 3} and tartaric acid on Ni.
