Abstract
The quasi-one dimensional conductors (PE)(2)X . 2/3THF (PE = perylene, X = PF6,AsF6;THF = tetrahydrofurane) and (PE)(4)(SbF6)(3) were studied by X-Ray scattering. For the PF6- and AsF6-salts the Peierls- and two further struc tural transitions are characterized by fixed film-fixed crystal exposures. (PE)(4)(SbF6)(3) shows modulated diffuse sheets of high intensity in recipr ocal space. Perylene and anion molecules form parallel separated stacks. Du e to weak correlation of neighbouring anion stacks a Peierls transition is prevented.
