Electrochemical oxidation of BEDT-TTF (bis (ethylenedithio) tetrathiafulvalene) in chloroform/carbon disulfide (3:1) in the presence of Bu₄NBr as a supporting electrolyte at low current density results in the (BEDT-TTF)₂Br3H₂0 crystal. Its composition has been established by chemical analysis (Br, C, H, S), XPS and IR. The temperature dependence of the resistance has been studied down to 26K at ambient pressure. This material has weakly metallic behavior above 230K, and becomes a semiconductor below this temperature. The structure of the complex is also described.
