Coexistence of Quasi-One- and -Two-Dimensional Electronic Structures in (EDO-TTF)2X (X = GaCl4, ReO4)

Abstract

Crystal structures and physical properties of (EDO-TTF)2X where EDO-TTF=ethylenedioxytetrathiafulvalene, X=GaCl4 and ReO4 were investigated. These isostructural salts belonged to triclinic system with space group P1, and. two kinds of the donor layers coexisted in a crystal. EDO-TTF formed head-to-tail and head-to-head type columnar structures in each donor layer, for which quasi-one- and -two- dimensional Fermi surfaces were calculated, respectively.
