Structural Proof for a Higher Polybromide Monoanion: Investigation of [N(C₃H₇)₄][Br₉]

Abstract

Bromine's nine: The first crystal structure of a higher polybromide monoanion, [NPr4][Br9] is reported along with its IR and Raman spectra (see picture). Owing to its low melting point and vapor pressure, this substance can be classified as an ionic liquid. It shows surprisingly high conductivity which may enable its applications as electrolyte in batteries. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
