A hint of superconducting transition has been observed for the first time in a cation radical salt derived from bisethylenethio-tetrathiafulvalene (BET-TTF), the salt (BET-TTF)2Br·3H2O. Here the synthesis, X-ray structure, and physical properties of two hydrated halides of BET-TTF that are isostructural and present stable metallic properties are described. The Figure is a perspective view of the crystal structure of (BET-TTF)2Br·3H2O, layers of BET-TTF radical cation alternating along the a-direction with polymeric anion networks.
