Abstract: The catalytic activities of [HnRu3(CO)9(CCO)]-(2-n)(n=0, 1, 2, 3) support-ed on oxides have been estimated using INDO calculations and correlation betweencatalytic activity and electronic structure for these clusters have been established.The activity in 13CO isotopic exchange strongly relates to the bond orders of Ru-CO and C-CO, and the activity in alkylation with nucleophile or electrophile de-pends mainly on the net charges at Cβ atoms.In addition, the possible species of [H3Ru3(CO)9(CCO)]+ has been proposed although it has not been synthesized upto now.
