摘要
Dimers of flat (EDO-TTF)+ molecules separated by bent neutral EDO-TTF (ethylenedioxytetrathiafulvalene) molecules are found in the insulator phase of (EDO-TTF)2PF6, 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.
