Abstract

X-ray single crystal diffraction study of two new molecular conductors α′′-(BEDO-TTF)2Cl·3H2O and θ-(BDH-TTP)2(Br0.67Cl0.33)·3H2O has been carried out. Both crystals have a layered structure: conducting layers of organic π-electron donors BEDO-TTF or BDH-TTP are separated by complex anion layers. The anion part is presented by honeycomb-like network composed by hydrogen-bonded halogen anions Cl¯ (Br¯) and the water molecules. According to the electronic band structure calculations, a metal-like behavior of conductivity is expected within the organic α′′-BEDO-TTF and θ-BDH-TTP layers.
