Description
Summary:•A procedure for the synthesis of the anhydrous CeF4 by the reaction between CeF3 and XeF2 was proposed.•Characterization of the forming CeF4 was carried out by XRD, FTIR, 19F NMR and thermogravimetry.•The anhydrous CeF4 was found to undergo hydration when exposed to air.•An approximate formula [CeF4•0.2H2O]*0.7H2O for the crystalline hydrate, formed after exposure to air, was proposed. By reacting CeF3 with XeF2 the anhydrous CeF4 was synthesized and studied by XRD, SEM, FTIR, 19F NMR spectrometry and thermogravimetry. It was found that CeF4 undergoes hydration upon keeping in air forming the crystalline hydrate with the approximate formula [CeF4•0.2H2O]*0.7H2O. Water molecules both enter the coordination sphere of cerium and form crystalline hydrates with cerium(IV) fluoride due to OH…F hydrogen bonds in the crystal lattice. [Display omitted]
