Abstract

The electrochemical oxidation of BEDT-TTF with Hg(SCN)2, KSCN, and 18-crown-6 ether yielded two different BEDT-TTF salts of mercury(II) thiocyanate depending on the solvent used. The K+ containing salt, (BEDT-TTF)2[KHg(SCN)4], was metallic down to 1.5 K with various temperature dependences. The crystal structures showed an alternating stacking of two-dimensional networks of BEDT-TTF molecules and of KHg(SCN)4 anions. The other modification (BEDT-TTF)3[Hg(SCN)3] exhibited metal-insulator (MI) transition at around 180 K.
