Abstract :
Four bis(ethylenediseleno) tetrathiafulvalene (BEDSe-TTF)-based salts, (BEDSe-TTF)2Hg2X2 (X=I. Br), (BEDSe-TTF)4Hg3Br8 · C2H3Cl3 and (BEDSe-TTF)4Hg3Br4 · 1.5C2H3Cl3, have been prepared by electrocrystallization. Two of them. (BEDSe-TTF)2Hg2X6, have been characterized by X-ray crystallography. The triclinic (space group Pī) room-temperature lattice parameters when X=I are: a = 6.798(4),b = 10.728(7), c 15.905(9) Å, α=106.33(6)°, ß=99.78(4)°, γ-92.97(5), V = 1090(1) Å3. When X =Br the parameters are: a=6.665(3), b= 10.314(5), c=15.720(7) Å, α-105.70(4)°, ß=99.65(4)°, γ=93.79(4)°, V = 1018(1) Å3. At room temperature, (BEDSe-TTF)4Hg3Br8 · C2H3Cl3 is metallic and the others are semiconductors.
