M. Scharwitz, T. van Almsick and W. S. Sheldrick

Abstract: The cation of the title compound, [Ir(C₁₀H₁₅)(C₄H₈NO₂S)](CF₃SO₃)·0.5H₂O, contains a half-sandwich [Ir(C₅Me₅)]²⁺ fragment, the Ir^III atom of which is coordinated by the tridentate S-methylcysteinate ligand (S-MecysO) in a ³N,O,S manner. An R_Ir configuration is observed for the transition metal and an S_S configuration for the chiral thioether S atom.
