| Abstract: | In this paper the transmission EXAFS and IR study for tetranuclear cobalt cluster Co4 (CO)10 (PPh)2 and its supported cluster on silica Co4/SiO2 before and after olefin hydroformylation is reported. The structural parameter such as the atom kinds surrounding cobalt, the coordination numbers(N) and the radial distances (R) between the cobalt and its neighbouring atoms have been determined, and the relation between catalytic activity and structure has been discussed.
It may be concluded that: the bridging carbonyl numbers increases from 2 to 4 as Co4 (CO)10 (PPh)2 changes to Co4/SiO2, but the framework structure and the terminal carbonyl coordination number of the tetranuclear cobalt cluster are the same as the results of Co4 (CO)_(10) (PPh)_2. |
