Abstract
Crystal structures and electrical properties of BETS compounds with te trahedral anions, MX4- (BETS = bis(ethylenedithio)tetraselenafulvalene ; M = Ga, Fe, In; X = Cl, Br) were examined. Every kappa-type salt is metallic below 50 K. Lambda-(BETS)2FeCl4, which is isomorphous to the superconductor GaCl4 salt, undergoes a sharp metal-insulator transitio n at 8 K.
