The reactions of [Fe<inf>2</inf>(CO)<inf>6</inf>(μ-Cl)(μ-CPh=CHPh)] with LiSR (R = Et, Pr<sup>i</sup>, cyclo-C<inf>6</inf>H<inf>11</inf>, Ph, or CH<inf>2</inf>Ph) lead to the complexes [Fe<inf>2</inf>(CO)<inf>6</inf>(μ-SR)(μ-CPh=CHPh)]. The structure of the benzyl derivative has been established by X-ray diffraction methods; crystals are monoclinic, space group P2<inf>1</inf>/n with a = 21.383(3), b = 7.098(2), c = 16.856(3), Å, β = 95.49(2)°, and Z = 4. The structure was solved and refined on the basis of 2 197 significant counter data, to a final R value of 0.056. The structure consists of Fe<inf>2</inf>(CO)<inf>6</inf> units with benzylthiolato and σ:η<sup>2</sup>-diphenylethenyl ligands bridging the two metal centres.
