Study in Coordination Substitution of Trinuclear Iron and Ruthenium Clusters by Infrared and Ultraviolet Spectroscopy

In this paper, ultraviolet spectra and infrared spectra were used in the characterization of the reaction in which carbonyls in trinuclear-iron cluster and trinuclear-ruthenium cluster were substituted by Ph2C2 and PPh3 respectively. The spectra showed the process of the new compounds appear and starting materials disappear separately. Infrared spectra data in KBr pellets further proved the result products. Reaction of Ru3(CO)12 with PPh3 (mol ratio = 1:3) in hexane affords Ru3(CO)9 (PPh3)3, a red microcrystalline solid and Fe3(CO)12 with Ph2C2 (mol ratio = 1:1) affords Fe3(CO)10 (Ph2C2) a deep green crystals. In the study, the ultraviolet spectra and infrared spectra of reaction solutions changed following the reactions, given a information in which we known the reaction starting and finishing. Then new compounds possibly were separated from reaction solutions. This is an important method used for synthesis and catalysis.
