Abstract: Reaction of triphenylphosphine with(μ-n-C4H9S)(μ-CH3OCH2CH2S)Fe2(CO)6,whichwas prepared from a conjugated addition reaction of(μ-BrMgS)(μ-n-C4H9S)Fe2(CO)6 with,CH2=CHOCH3 followed by an alcoholysis process,gave the title complex of (μ-n-C4H9S)·(μ-CH3OCH2CH2S).The crystals of the title complex are monoclinic, spacegroup C2/c,with α=30.892(4)Å,b=12.454(2)Å,c=25.725(4)Å;β=91.46(1)°,V=9893.7Å3;Z=8;Dc=1.284g/cm3;R=0.060. The cluster core of this complex consists of twoiron and two sulfur atoms with a butterfly configuration. Two triphenyl phosphine ligands are trans to Fe-Fe bent bond. The substituents are attached to sulfur atoms by e-bonds.
