Charge-Ordering and Structural Transition in the New Organic Conductor δ'-(BEDT-TTF)₂CF₃CF₂SO₃.

ABSTRACT: We report structural, transport, and optical properties and electronic structure calculations of the δ'-(BEDT-TTF)₂CF₃CF₂SO₃ (BEDT-TTF = bis(ethylenedithio)tetrathiafulvalene) organic conductor that has been synthesized by electrocrystallization. Electronic structure calculations demonstrate the quasi-one-dimensional Fermi surfaces of the compound, while the optical spectra are characteristic for a dimer-Mott insulator. The single-crystal X-ray diffraction measurements reveal the structural phase transition at 200 K from the ambient-temperature monoclinic P2₁/m phase to the low-temperature orthorhombic Pca2₁ phase, while the resistivity measurements clearly show the first order semiconductor-semiconducto
