Fluorine-Rich Fluorides: New Insights into the Chemistry of Polyfluoride Anions

Angew Chem Int Ed Engl. 2015 Jul 6;54(28):8279-83. doi: 10.1002/anie.201502624. Epub 2015 Jun 3.

Abstract

Polyfluoride anions have been investigated by matrix-isolation spectroscopy and quantum-chemical methods. For the first time the higher polyfluoride anion [F5 ](-) has been observed under cryogenic conditions in neon matrices at 850 cm(-1) . In addition, a new band for the Cs(+) [F3 ](-) complex in neon is reported.

Keywords: cesium fluorides; coupled-cluster calculations; fluorides; matrix-isolation spectroscopy; polyfluoride anions.
