High oxidation state fluoro–rhenium species: preparation and characterization of [ReF6]+, [ReF4O]+, and [Re2F9O2]+, and the crystal structure of [Re2F9O2]+[Sb2F11]–
Abstract
The fluoride ion donor properties of ReF7 and ReF5O have been demonstrated by the preparation of the adducts [ReF6]+[Sb3F16]–, [ReF6]+[Sb3F16]–, [ReF4O]+[AsF6]–, and [Re2F9O2]+[Sb2F11]–, which have been characterized by vibrational spectroscopy, mass spectrometry, and chemical analysis. The crystal structure of [Re2F9O2]+[Sb2F11]– consists of discrete fluorine-bridged dimeric anions, both of which consist of two bridged octahedra.
