Photochemistry with Chlorine Trifluoride : Syntheses and Characterization of Difluorooxychloronium(V) Hexafluorido(non)metallates(V), [ClOF2][MF6] (M=V, Nb, Ta, Ru, Os, Ir, P, Sb)
Abstract
<p>A photochemical route to salts consisting of difluorooxychloronium(V) cations, [ClOF<sub>2</sub>]<sup>+</sup>, and hexafluorido(non)metallate(V) anions, [MF<sub>6</sub>]<sup>−</sup> (M=V, Nb, Ta, Ru, Os, Ir, P, Sb) is presented. As starting materials, either metals, oxygen and ClF<sub>3</sub> or oxides and ClF<sub>3</sub> are used. The prepared compounds were characterized by single-crystal X-ray diffraction and Raman spectroscopy. The crystal structures of [ClOF<sub>2</sub>][MF<sub>6</sub>] (M=V, Ru, Os, Ir, P, Sb) are layer structures that are isotypic with the previously reported compound [ClOF<sub>2</sub>][AsF<sub>6</sub>], whereas for M=Nb and Ta, similar crystal structures with a different stacking variant of the layers are observed. Additionally, partial or full O/F disorder within the [ClOF<sub>2</sub>]<sup>+</sup> cations of the Nb and Ta compounds occurs. In all compounds reported here, a trigonal pyramidal [ClOF<sub>2</sub>]<sup>+</sup> cation with three additional Cl⋅⋅⋅F contacts to neighboring [MF<sub>6</sub>]<sup>−</sup> anions is observed, resulting in a pseudo-octahedral coordination sphere around the Cl atom. The Cl−F and Cl−O bond lengths of the [ClOF<sub>2</sub>]<sup>+</sup> cations seem to correlate with the effective ionic radii of the M<sup>V</sup> ions. Quantum-chemical, solid-state calculations well reproduce the experimental Raman spectra and show, as do quantum-chemical gas phase calculations, that the secondary Cl⋅⋅⋅F interactions are ionic in nature. However, both solid-state and gas-phase quantum-chemical calculations fail to reproduce the increases in the Cl−O bond lengths with increasing effective ionic radius of M in [MF<sub>6</sub>]<sup>−</sup> and the Cl−O Raman shifts also do not generally follow this trend.</p>
