摘要：
(Ethylenedioxytetrathiafulvalene)(2)PF6 shows a first order Metal-Insulator transition at around 280 K, of which mechanism implies the cooperative features of Peierls, charge ordering, and anion ordering transitions with the large molecular deformation. The anisotoropic thermal contraction of the crystal structure is described along with the freezing of the anion disorder observed at 110 K.
