Figure 8
(a) Side view of the EDT-TTF-I₂ tetramers, showing the distortions from planarity of the essentially neutral donors A (in red), interacting with oxidized B molecules (in blue). (b) Projection view of the AB and BB overlaps within the tetramer, showing the eclipsed BB overlap characteristic of dicationic dimers.
