BETS salts (where BETS is bis(ethylenedithio)tetraselenafulvalene) wit
h the CuCl3, Cu2Cl6, (CuCl4)(n) and Fe0.75Ga0.25Cl4 anions have been s
ynthesized. The physical properties of theta-BETS(4)Cu(2)Cl(6) and kap
pa-BETS(2) (Fe0.75Ga0.25Cl4) salts and crystal structures of theta-BET
S(4)Cu(2)Cl(6) have been studied. Both compounds have been found to ex
hibit Shubnikov-de Haas and angle-dependent magnetoresistance oscillat
ions.
