The reaction of with pyridine-2-thione (pySH) at room temperature gives the tungsten(II) compound (1) and the tungsten(0) compound (2).To slow the rate of intramolecular exchange of the pyS ligands in (1), PMe2Ph was introduced to give (4).Crystals of (4) are monoclinic, space group C2/c,a = 30.738(9), b = 9.867(2), c = 16.048(9) Angstroem, β = 121.04(3) deg, and Z = 8, and the X-ray structure was refined to R = 0.0330 and R'= 0.0335.Molecules of (4) contain two chelating pyS ligands and the tungsten is seven-co-ordinated.Approximately determined exchange rates for the diastereotopic Me groups of PMe2Ph and of the non-equivalent pyS ligands are the same indicating that both exchanges result from the same process.The corresponding molybdenum compound is isostructural and shows similar fluxionality.
