The reaction of Fe3(CO)12 and bulky thiols HSR (R = C6H2iPr3-2,4,6; C6H2Me3-2,4,6) in toluene yielded compounds [Fe2(CO)6(μ-SR)2] (R = C6H2iPr3-2,4,6 (1), C6H2Me3-2,4,6 (2)). The substitution of one carbonyl by the phosphine Ph2P(CH2)2Si(OEt)3 in complex 1 afforded {Fe2(CO)5[Ph2P(CH2) 2Si(OEt)3](μ-SC6H2 iPr3-2,4,6)2} (3). Mononuclear compounds [(η5-C5H5)Fe(CO)2(SC 6H2iPr3-2,4,6)] (4) and {(η5-C5H5)Fe(CO)[Ph2P(CH 2)2Si(OEt)3](SC6H2 iPr3-2,4,6)} (5) have also been obtained. Compound 1 has been studied by X-ray diffraction and the structure determined reveals a distorted octahedron geometry around each iron atom and confirms the anti arrangement of R substituents, R = C6H2iPr3-2,4,6, in the molecule. The preparation of thiol HSC6H2iPr3-2,4,6 yielded the disulfide (C6H2iPr3-2,4,6)2S 2 as a by-product, whose structure has been solved by X-ray diffraction.
