A new and improved synthetic route to WSF4 was developed from the reaction of WF6 and Sb2S3 in anhydrous HF. Tungsten sulfide tetrafluoride was characterized by Raman and 19F NMR spectroscopy for the

The compound WSF4 was synthesized in one step by the reaction of WF6 with (Me3Si)2S in solution at ambient temperatures. Solution-phase structural data have been obtained for the first time for it and related tungsten chalcogenide tetrahalides via a tungsten L(III)-edge EXAFS (extended X-ray absorption fine structure) study. This demonstrates that WOF4, WOCl4 and WSF4 in acetonitrile or dichloromethane solution are monomeric. For WSF4 analysis of the EXAFS data yielded bond lengths of 2.026(8) (W=S) and 1.863(3) A (W-F). The W=S bond length is shorter than previously determined, by gas-phase electron diffraction, but is more consistent with that found in related structures.

The molecular structure of WSF4 has been studied by gas-phase electron diffraction at an average nozzle temperature of 232°C. The experimental data are fitted by a square-pyramidal model of C4υ, symmetry in which the tungsten atom is above the plane of the four fluorine atoms. The distances and angles are ra(W=S) = 2.104 (7) A?, ra(W-F) = 1.847 (3) A?, ∠S=W-F = 104.5 (11)°, and ∠F-W-F = 86.6 (5)°. The estimated uncertainties are 2σ.
