BETS salts (where BETS is bis(ethylenedithio)tetraselenafulvalene) with the CuCl 3, Cu 2Cl 6, (CuCl 4) n and Fe 0.75Ga 0.25Cl 4 anions have been synthesized. The physical properties of $\theta$-BETS 4Cu 2Cl 6 and $\kappa$-BETS 2(Fe 0.75Ga 0.25Cl 4) salts and crystal structures of $\theta$-BETS 4Cu 2Cl 6 have been studied. Both compounds have been found to exhibit Shubnikov-de Haas and angle-dependent magnetoresistance oscillations.
