Metal cluster chemistry is an active studying field nowadays. It is possible that metal clusters can be developed as new homogeneous catalysts with special functions. Organoiron clusters, which could be easily synthesized at lower price, are very important in metal cluster chemistry. Fe_3(CO)_(12) is a very useful compound with higher activity than Fe(CO)_5 in the Metal cluster chemistry is an active studying field nowadays.
