Crystal structure, transport and magnetic properties of (EDS-TTF)₂FeBr₄ (EDS-TTF: ethylenediselenotetrathiafulvalene) are reported. Between one-dimensional columns of donors and quasi square-lattices of FeBr₄ anions, close Br⋯Se van der Waals contacts and CH⋯Br type hydrogen bonds are observed. This salt shows high room-temperature conductivity and metal-insulator transition at ca. 250K (σ_RT = 400 S cm^-1, E_A = 380 K). The magnetic susceptibility obeys the Curie-Weiss law (C = 4.58 emu K mol^-1, Θ = -0.9 K) without showing any magnetic transition down to 1.8 K. The weak π-d interaction can be due to the small contribution of Se 4p orbitals to the HOMO of EDS-TTF.
