The thermal behaviour of [(η-C5H5)Fe(CO)2]2 adsorbed on partly dchydroxylated alumina and silica surfáces has been followed by FT-IR spectroscopy in the temperature range of 303-723 K. The main products of surface reactions were the vcry stable tetrameric [(η-C5H5)Fe(μ-CO)]4 and the less stable monomeric (η-C5H5)Fe(CO)2(-O-) species. On alumina traces of 1:1 and 1:2 adducts of [(η-C5H5)Fe(CO)2]2 with surface Lewis acidic sites, while on silica traces of the 1:2 hydrogen bonded complex and oxidized monomeric cation [(η-C5H5)Fe(CO)3]+ were also detected.
