Preparation and study by raman spectroscopy of KrF2·MOF4, XeF2·MOF4, and XeF2·2MOF4 (M = Mo, W) and a solution 19F NMR study of KrF2·nMoOF4 (n = 1-3) and KrF2·WOF4

The first krypton difluoride-metal oxide fluoride adducts have been prepared by reaction of KrF2 with MOF4 (M = Mo, W) in SO2ClF solution at low temperatures. The 19F NMR spectra of KrF2·nMoOF4 (n = 1-3) and KrF2·WOF4 in solution show that they are best formulated as essentially covalent structures containing Kr?F?M bridges and mononuclear or polynuclear metal oxide fluoride moieties. Studies of equilibria involving Kr-O-W- and Kr?F?W-bridged species have been interpreted to suggest that stable krypton-oxygen bonds are unlikely. Raman spectra of the solid KrF2·MOF4 (M = Mo, W) adducts have been compared with those of the analogous xenon compounds and all have been interpreted in terms of covalent fluorine-bridged structures. The Raman spectra of the solid adducts XeF2·2MOF4 are also reported.
