The preparation and characterisation of XeF2.WOF4 and XeF2.2WOF4 by 19F nuclear magnetic resonance and Raman spectroscopy. Examples of non-labile xenon–fluorine–metal bridges.

Abstract

Raman and ¹⁹F n.m.r. spectroscopy show that the adducts XeF₂·WOF₄ and XeF₂·2WOF₄, both in the solid state and in solution, are best formulated as covalent structures containing XeFW bridges. ¹⁹F n.m.r. spectra of XeF₂·2WOF₄ dissolved in SO₂CIF also show that complex equilibria involving Xe-O-W and XeFW bridged species occur.
