The first tetrafluoroborate compound with XeF2 coordinated to a metal center, [Cd(XeF2)](BF4)2, has been synthesized. It crystallizes in monoclinic space group P21/a with a = 8.785(11) A, b = 9.079(2) A, c = 10.718(6) A, beta = 110.824(6), and Z = 4. Its crystal structure and that of Cd(BF4)2 have been solved. The latter crystallizes in orthorhombic space group Pbca. Both syntheses were performed in aHF as solvent, at room temperature, yielding colorless solids. The Raman spectra of the solids are in harmony with the crystallographic findings. [Cd(XeF2)](BF4)2 has been shown to be in equilibrium with XeF2 and Cd(BF4)2 in aHF.

Coordination of XeF₂to Calcium and Cadmium Hexafluorophosphates(V)

[M(XeF2)5](PF6)2 (M = Ca, Cd) complexes were prepared by the reaction of MF2 and XeF2 under pressure of gaseous PF5 in anhydrous HF as solvent. The coordination sphere of the Ca atom consists of nine fluorine atoms: three from two PF6(-) units (one bidentate and one monodentate) and one from each of six XeF2 molecules. The coordination sphere of the Cd atom consists of eight fluorine atoms: one from each of two PF6(-) units and one from each of six XeF2 molecules. Two of the XeF2 ligands about M in each compound are bridging ligands and are each linked to two M, generating infinite (-M-F-Xe-F-M-F-Xe-F-) chains along the b-axis in the Ca salt and along the c-axis in the Cd compound. The Cd2+ cation is smaller and more electronegative than the Ca2+ cation. These differences account for the higher F ligand coordination in the Ca2+ salt and for other structural features that distinguish them. The different stoichiometry of the PF6(-) salts when compared with their AsF6(-) analogues, which have the composition [M(XeF2)4](AsF6)2 (M = Ca, Cd), is in accord with the lower F ligand charge in the AsF6(-) when compared with that in the PF6(-) compound. Indeed, the AsF6(-) ligand charges appear to be similar to those in the XeF2-bridged species.

“…For the INS measurements, highly enriched (>99.9%) xenon gas was converted to solid XeF 2 . XeF 2 was prepared by a photochemical [7] or a thermal [8] reaction of F 2 and Xe gases in excess Xe; an excess of Xe gas is required in order to ensure only the difluoride is produced rather than the tetrafluoride and hexafluoride as well. From the syntheses, 6.80 g of 130 XeF 2 and 9.89 g of 132 XeF 2 were obtained.…”

0+states inXe130,132: A search for E(5) behavior

The level structures of 130,132 Xe were studied with the inelastic neutron scattering reaction followed by γ-ray detection. Level lifetimes were measured using the Doppler-shift attenuation method and low-lying excited states in these nuclei were characterized. With a focus on the decay properties of the 0 + states, these nuclei were examined as representations of the E(5) critical-point symmetry.
