Abstract

Initial steps of the interaction of Ru3(CO)12, Fe3(CO)12, Fe2Ru(CO)12 and H2FeRu3(CO)13 clusters with hydrated alumina surfaces have been studied by FT-IR spectroscopy combined with data handling procedures. The first stage of the interaction is a pure physisorption. At the second stage the metal-metal bonds split producing a large variety of mobile subcarbonyls. In the case of Fe3(CO)12 the subcarbonyls form molecular Fe(CO)5, while at the bimetallic clusters they form molecular Fe- (CO)5 and Ru3(CO)12. Fe(CO)5 loses CO ligands producing Fe2+ and Fe3+ anchored ions. Ru3(CO)12, through further intermediate subcarbonyls, slowly decomposes into incipient anchored species RuO- (CO)2, RuII(CO)2 and RuIII(CO)2.
