Transition-metal thiofluorides; preparation of WSF4 and related anions

Abstract

¹⁹ F N.m.r., i.r., and Raman spectroscopy and mass spectrometry show that WSF₄ is the main product of the reaction of WF₆ with Sb₂S₃; reactions of solutions of WSCl₄ in MeCN with XeF₂ give ¹⁹F n.m.r. spectra attributable to WSF₄, WSF₃Cl, WSF₂Cl₂, and WSFCl₃, and with HF to WSF₄, WSF₅^–, WSF₄Cl^–, WSF₃Cl₂^–, WSFCl₄^–, and W₂S₂F₉^–.
