Abstract

Hydrido carbonyl clusters represent powerful molecular models for the co-adsorption of carbon monoxide and hydrogen on metal surfaces, a key step in several catalytic processes. Over the past two decades a considerable number of such species have been reported in the literature. In this paper, the structural chemistry of high nuclearity osmium and ruthenium hydrido carbonyl clusters is critically reviewed. Particular emphasis is placed on the limits of the various indirect methods of hydride location in clusters, and an alternative interpretation of the results of spectroscopic studies performed for samples of some Ru and Os clusters in solution is given.
