OBSERVATION AND EVALUATION OF THE SYNCHRONOUS LIGAND ATOM PYRAMIDAL INVERSIONS IN BINUCLEAR RHENIUM CARBONYL HALIDE COMPLEXES OF DISULPHIDES AND DISELENIDES: AN X-RAY CRYSTAL STRUCTURE OF

The dinuclear complexes (X = Cl or Br, R = Ph or Me3Si, E = S or Se) have been prepared and characterized.A variable temperature 1H NMR study on these complexes demonstrated the pyramidal atomic inversion process at the coordinated sulphur and selenium atoms.Total band-shape fittings were used to yield activation parameters for the rate process, in which the two sulphur or selenium atoms undergo synchronous or correlated inversion.
