Structure of bis(ethylenedithio)tetrathiafulvalenium tribromodicuprate(I), (BEDT-TTF+)CuI2Br3: coordination of the organic radical cation to the metal ions

Abstract

X-Ray crystal analysis has revealed that two sulfur atoms of a bis(ethylenedithio)tetrathiafulvalene radical cation, BEDT-TTF⁺, are coordinated to copper(I) atoms in a –Cu–Br–Cu–(µ-Br)₂–Cu– chain, in which each copper atom has a distorted tetrahedral coordination with a sulfur atom and three bromine atoms.
