Abstract

Abstract The complexes [M (CO) 5 (RSCH 2 SR)](M Cr, R Et, i Pr, t Bu; M W, R Me, Et, i Pr, 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 [W (CO) 5 (t BuSCH 2 S t Bu)] was obtained.
