The anions of the cluster salt 3-SR)> (R = t-C4H9 (I); R = C6H11 (II)) react with monohalides XCl (X = PR'2, AsR'2, SbR'2, SR', SeR'; R' = Alkyl, Aryl) to give the neutral complexes Fe3(CO)9(μ₃-SR)(μ₂-X) (III-XII).X-ray analyses show that in these products one of the Fe-Fe bonds is opened and bridged by the μ₂-ligand X.In some cases, the synthesis of the trinuclear clusters is accompanied by formation of the dinuclear species Fe2(CO)6(μ₂-SR)(μ₂-X) (X = PPh2, (XIII); X = SPh, (XIV)) as by-products.In a formal sense this corresponds to loss of an Fe(CO)3 group from the trinuclear complexes.The geometry of Fe2(CO)6(μ₂-SC6H11)(μ₂-PPh2) (XIII) has been elucidated by X-ray analysis.
