摘要
BETS (=bis(ethylenedithio)tetraselenafulvalene) conductors with M(CN)(4) anions (M=Pd, Pt) are metallic down to 4K. Crystals of MCl4 salts (M=Co, Ni, In) are metallic down to 4 K. BETS2InCl5[(C2H5)(4)N](0.7) undergoes a gradual metal-insulator transition around 50 K. The magnetic susceptibility of BETS4Cu2Cl6 exhibits a round maximum showing an antiferromagnetic interaction between Cu2+ in Cu2Cl62- anions (J=163 K). The electrical properties and crystal structures of BETS complexes with M(dts)(2) (M=Au, Pd, Pt; dts=dithiosquarate) are briefly mentioned.
