Several new salts of TTF derivatives with organic anions were obtained. In this proceeding, we present the crystal structure and properties of $\beta
$ '-(EDT-TTF-CONHMe) 2[ (E)-HO 2C-CH=CH-CO 2] , in which hydrogen bonds both link the anions among themselves and to the cations. This salt is a semiconductor with a room-temperature of 0.3 S cm -1. Key words. Tetrathiafulvalenes, cation radical salts, carboxylates, hydrogen bond.
