HETEROMETALLIC SULFIDO CLUSTERS BY METAL EXCHANGE - SYNTHESES AND X-RAY CRYSTAL-STRUCTURES OF (ETA(5)-C5H4CH3)MOFECO(CO)(8)(MU(3)-S) AND (ETA(5)-C5H4CH3)(2)MO2FE(CO)(7)(MU(3)-S)

Heterometallic sulfido clusters (eta(5)-C5H4CH3)MoFeCo(CO)(8)(mu(3)-S) and (eta(5)-C5H4CH3)(2)Mo2Fe(CO)(7)(mu(3)-S) were obtained through metal exchange with electrophilic addition-elimination via substitution from the reaction of HFe2Co(CO)(9)(mu(3)-S) with (eta(5)-C5H4CH3)Mo(CO)(3)Cl in THF. The title clusters were characterized by elemental analyses, and IR and NMR spectroscopies. The X-ray crystal structures of the title clusters are reported here as well.
