Abstract

Abstract: Herein we report the synthesis and structural characterization of four novel polychloride compounds. The compounds [CCl(NMe2 )2 ][Cl(Cl2 )3 ] and [NPr4 ][Cl(Cl2 )4 ] have been obtained from the reaction of the corresponding chloride salts with elemental chlorine at low temperature. They are the missing links in the series of polychloride monoanions [Cl(Cl) n ] − ( n =1–6). Additionally, the reaction of decamethylferrocene with elemental chlorine was studied yielding [Cp*2 Fe]2 [Cl20 ], which contains the largest known polychloride [Cl20 ] 2− to date, and [Cp*2 Fe][Cl(Cl2 )4 (HF)], which is the first example of a polychloride‐HF network stabilized by strong hydrogen and halogen bonding. All compounds have been characterized by single‐crystal X‐ray diffraction, Raman spectroscopy and quantum‐chemical calculations. Abstract : Polyhalides have many applications in various fields of chemistry and show a surprising structural diversity. In this work the synthesis and characterization of four novel polychloride anion is presented. This includes a [Cl20 ] 2− ion, which represents the largest known polychloride, as well as a [Cl(Cl2 )4 HF] − anion which is the first example of a polyhalide HF network.
