Dimers of flat (EDO‐TTF) + molecules separated by bent neutral EDO‐TTF (ethylenedioxytetrathiafulvalene) molecules are found in the insulator phase of (EDO‐TTF) 2 PF 6 , but not in that of the metallic phase. The cooperativity of Peierls distortion, charge ordering, and anion ordering in this metal–insulator transition can be regarded as the result of a molecular displacement.
