The decahexacarbonylhexarhodium cluster reacts with dimethylsulfide to give a series of substituted clusters , x = 1-4 (1-4).The crystal structures of 1 and 4 have been determined.The SMe2 ligands replace terminal carbonyls, otherwise the cluster structure is maintained.The four sulfide ligands in 4 replace four carbonyl groups at Rh atoms in the same plane of the Rh6 octahedron, with the SMe2 groups lying alternately above and below this plane.The di- and tri-substituted species have been characterized by ir spectroscopy and elemental analysis.The reactivity of toward hydrogen and carbon monoxide has been studied.Under CO it undergoes replacement of SMe2 by carbon monoxide to afford .In a corresponding reaction with H2 is converted into a mixture of 2-4.Hydrogenation of 1-hexene using as a catalysts precursor was observed at 60 degC with a highest rate of 2200 turnovers/h.
