英文摘要	A new BEDT-TrF-based cation radical salt, alpha'-(BEDT-TTF)(2)C6H4 (SO3)(2) [BEDT-TTF = bis-(ethylenedithio) tetrathiafulvalene, C6H4(SO3)(2)(2-) = p-disulfonate benzene], has been prepared by oxidative electrocrystallization at a constant current of 1.5 muA. The single crystal structure was determined by four-circle X-ray diffraction method. The crystal belongs to monoclinic system, P2/n space group with the unit cell parameters of a = 0.77937(17) nm, b = 0.66989(11) nm, c = 3.4422(7) nm, beta = 91.135(12)degrees, V = 1.7968(6) nm(3). In the crystal of the title compound, the BEDT-TTF cation radicals are stacked to form staggered columns of dimerised BEDT-TTF units along the a-axis and arranged side-by-side to form one-dimensional uniform chains along the b-axis. Counter ions are also arranged to form strong interactions along a-axis. axis. Layers of BEDT-TTF cationic radicals and C6H4(SO3)(2)(2-) counter anions alternate to form separate structure along the c-direction. The room temperature conductivity of alpha'-(BEDT-TTF)(2)C6H4(SO3)(2) was measured to be 0.5913 Omega(-1).m(-1). The resistivity-temperature curve demonstrates that it is a typical semiconductor. A certain transition took place around 150 K.
