The complexes [M(CO)5(RSCH2SR)] (M Cr, R Et, iPr, tBu; M W, R Me, Et, iPr, tBu) were synthesised. Total bandshape NMR analysis was used to measure energies of inversion of the coordinated S atom in the tungsten complexes. ΔG‡ (298.15 K) values were in the range 34–42 kJ mol−1. An X-ray structure of [W(CO)5(tBuSCH2StBu)] was obtained.
