Crystal and electronic structures of organic conductors,(EDT-TTF) 2 X (EDT-TTF= ethylenedithiotetrathiafulvalene; X= PF 6, AsF 6, TaF 6, BF 4, ClO 4, ReO 4, Au (CN) 2), have been studied. In all these compounds, the donor molecules exhibit face-to-face stacking. Simple tight-binding band calculations indicate quasi-one-dimensional electronic structures.
