“…[28] Ž emva and colleagues used the very powerful oxidant KrF 2 to react with AgF 2 and NiF 2 in HF in the presence of XeF 6 at Ϫ60°C and produced the solids [XeF 5 ϩ Ag III F 4 Ϫ ] [29] and [(Xe 2 F II ϩ ) 2 Ni IV F 6 2Ϫ ]. [30] XeF 6 ionises extensively in HF to form XeF 5 ϩ and F Ϫ , providing both the basic HF solution necessary for the formation of the high oxidation state anions in solution and the counterions XeF 5 ϩ and Xe 2 F II ϩ for isolation of the solid products. More recently Bartlett has reported quantitative oxidation of NiF 2 and AgF 2 to [Ni IV F 6 2Ϫ ] [31] and [Ag III F 4 Ϫ ] [32] at room temperature using ultra violet Ϫ or sunlight Ϫ irradiated F 2 in very strongly basic HF (KF/ HF ഠ 1:4).…”

Molten mixtures of XeF6 and CrVIOF4 react by means of F2 elimination to form [XeF5][Xe2F11][CrVOF5]⋅2 CrVIOF4, [XeF5]2[CrIVF6]⋅2 CrVIOF4, [Xe2F11]2[CrIVF6], and [XeF5]2[CrV2O2F8], whereas their reactions in anhydrous hydrogen fluoride (aHF) and CFCl3/aHF yield [XeF5]2[CrV2O2F8]⋅2 HF and [XeF5]2[CrV2O2F8]⋅2 XeOF4. Other than [Xe2F11][MVIOF5] and [XeF5][MVI2O2F9] (M=Mo or W), these salts are the only Group 6 oxyfluoro‐anions known to stabilize noble‐gas cations. Their reaction pathways involve redox transformations that give [XeF5]+ and/or [Xe2F11]+ salts of the known [CrVOF5]2− and [CrIVF6]2− anions, and the novel [CrV2O2F8]2− anion. A low‐temperature Raman spectroscopic study of an equimolar mixture of solid XeF6 and CrOF4 revealed that [Xe2F11][CrVIOF5] is formed as a reaction intermediate. The salts were structurally characterized by LT single‐crystal X‐ray diffraction and LT Raman spectroscopy, and provide the first structural characterizations of the [CrVOF5]2− and [CrV2O2F8]2− anions, where [CrV2O2F8]2− represents a new structural motif among the known oxyfluoro‐anions of Group 6. The X‐ray structures show that [XeF5]+ and [Xe2F11]+ form ion pairs with their respective anions by means of Xe‐ ‐ ‐F–Cr bridges. Quantum‐chemical calculations were carried out to obtain the energy‐minimized, gas‐phase geometries and the vibrational frequencies of the anions and their ion pairs and to aid in the assignments of their Raman spectra.

The complex [XeF5]3[Ti4F19] was prepared by reaction of XeF2, TiF4 and UV‐irradiated elemental fluorine in anhydrous hydrogen fluoride as the solvent. The crystal structure of [XeF5]3[Ti4F19] consists of [XeF5]+ cations and discrete [Ti4F19]3– anions. The [XeF5] units have usual slightly distorted pseudo‐octahedral symmetry. Contrary to the previously reported [Ti4F18]2– anion, where each TiF6 octahedron shares three apexes with three other octahedra, in [Ti4F19]3–, only two μ3‐[TiF6] octahedra share three apexes with three other [TiF6] units. Each of the remaining two μ2‐[TiF6] octahedra shares only two vertices with two of the above‐mentioned μ3‐[TiF6] moieties. The Raman spectrum of [XeF5]3[Ti4F19] is in agreement with the presence of [XeF5]+ cations and [Ti4F19]3– anions. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
