The complexes (M=Cr, R=Et, ⁱPr, t-Bu; M=W, R=Me, Et, ⁱPr, t-Bu) 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 was obtained.
