Sulfur-bridged Dimers Obtained from Μ-dithiobis(tricarbonyliron)
The reaction of SO2Cl2 with (μ-MS)(μ-ArS)Fe2(CO)6 (M = Li; Ar = Ph and M = MgBr; Ar = p-tolyl) results in oxidation of the latter and formation of SS bonded “dimers”. The “dimer” where Ar = Ph crystallizes in the space group P1 with a 10.584(4), b 11.247(1), c 14.275(3) Å, α 104.20(2), β 90.80(4), γ 98.12(2)°, V 1629 Å3 and Z = 2. Full matrix least-squares refinement yields a final R value of 4.4% based on 3986 independent reflections. The central SS bond is longer than that in elemental sulfur or in (μ-S2)Fe2(CO)6. © 1985.
