Infrared matrix isolation studies of the pentahalogermanate anions

Abstract: The gas-phase reaction of CsF with GeF, diluted in argon, followed by rapid condensation at 15 K into an inert matrix, has led to the formation of the GeF5anion ion paired with Cs'. At higher concentrations, the GeF6'anion was observed as well. The GeF5anion was characterized by Ge-F stretching modes at 679, 696, and 730 cm-', indicative of a trigonal-bipyramidal structure perturbed by the cesium counterion. The reactions of CsCl with GeF, and CsF with GeCI., gave rise to the Cs'GeClF; and Cs'GeCI,F ion pairs, respectively, but with decreasing yields. The synthesis of the GeCI,anion by the reaction of CsCl with GeC1, was not successful, indicating either marginal stability of this anion or an inherent limitation to the salt/molecule technique.
