Abstract

Charge-transfer salts of EDT-TTF with tetrahedral anions MX4 (M=Fe, Ga ; X=Cl, Br) were prepared. They are isostructural to each other (monoclinic P21/m) with the stoichiometry of 2:1. All of them are semiconductors having the conductivity at room temperature of 5 to 9 Scm−1 and activation energy of 40 to 170 meV. Since the calculated band structure of them indicate that they should be quasi one-dimensional metals, they were discussed from the point of structural deformation and strong electron correlation.
