| Abstract: | The reaction of complex [μ-SCH(CH3)CH(CH3)S-μ]Fe2(CO)6 (1) with trans-1,2-bis(diphenylphosphino)ethylene (trans-dppv) in the presence of Me3NO?2H2O in CH2Cl2/CH3CN afforded complex {[μ-SCH(CH3)CH(CH3)S-μ]Fe2(CO)5}2(trans-dppv) (2) with a bridging dppv. Complex [μ-SCH(CH3)CH(CH3)S-μ]Fe2(CO)4(cis-dppv) (3) was prepared by the reaction of 1 with cis-dppv and Me3NO?2H2O. The new complexes 2 and 3 were characterized by elemental analysis, spectroscopy, and X-ray diffraction analysis. |
