Abstract

The reaction of Na₂SO₃ with Fe(CO)₅/KOH in methanol forms the tetrahedral cluster [SFe₃(CO)₉]^2- in good yield. Acidification of [SFe₃(CO)₉]^2- with H⁺ forms the monohydrido cluster [SFe₃(μ-H)(CO)₉]^- (I) and the dihydrido cluster SFe₃(μ-H)₂(CO)₉. Further methylation of [SFe₃(CO)₉]^2- with MeSO₃CF₃ produces the sulfur-methylated cluster [MeSFe₃(CO)₉]^- (II). When [SFe₃(CO)₉]^2- is treated with Ru₃(CO)₁₂ in refluxing acetone, the octahedral cluster [SFe₂Ru₃(CO)₁₄]^2- (III) is obtained. Subsequent methylation of III with MeSO₃CF₃ gives the octahedral cluster [MeSFe₂Ru₃(CO)₁₄]^- (IV), in which the sulfur atom is pentacoordinated to one methyl group and two Ru and two Fe atoms. Clusters I-IV have been fully structurally characterized by spectroscopic methods and X-ray analysis. In this paper, the basic sites of [SFe₃(CO)₉]^2- are studied in terms of the differing electrophiles, and a novel pentacoordinate bonding mode of the sulfur atom is also found in cluster IV.
