A new bent donor based on ethylenedioxytetrathiafulvalene (EDO-TTF) and 1,3-diselenole group was synthesized and structurally characterized by elemental analysis, 1H NMR, 13C NMR, MALDI-TOF MS and X-ray single diffraction analysis. The crystal of the compound 1 belongs to monoclinic space group Pna21 with cell parameters a=1.8011(7) nm, b=2.0351(7) nm, c=0.4067(2) nm, Z=4, V=1.4907(10) nm3, Dc=2.176 g•cm-3, F(000)=944, μ=5.655 mm-1, R=0.0773, wR=0.1779 [I>2σ(I)]. Compound 1 displayed two reversible redox peaks corresponding to the TTF/TTF+• and TTF+•/TTF2+.
