Fourteen new PPh3 substituted Fe-S clusters,with general formula (μ-RS)(μ-R’S)Fe2(CO)5 PPh3,have been synthesized by reaction of unsymmetrical type of bis(μ-alkylthio ) hexacarbonyldiirons with triphenylphosphine.Based on the discussion of influence of PPh3 on VCO and alkyl spacial orientation of PPh3 in clusters has also been established.
