Charge-transfer interactions involving high oxidation state transitionmetal fluorides

Abstract

Charge-transfer interactions have been observed between NbF₅, MoF₆, and WF₆ and the Group IV compounds MX₄(M = Si, Ge, Sn, X = alkyl; M = C, Si, Sn, X = Cl) and between WF₆ and C₆H₆, C₆H₅CH₃, and C₆F₅. WF₅OMe behaves similarly to WF₆ but the spectra of phenoxotungsten (VI) fluorides are solvent independent. Photolysis of solutions of WF₆ in C₆H₆, C₆H₅CH₃, and Me₄Sn, leads to reduction of tungsten but pure products are not obtained.
