摘要：

Beta-(C10H8S8)2[CuCl2], M(r) = 903.8, triclinic, P1BAR, a = 6.623 (2), b = 9.723 (2), c = 12.658 (3) angstrom, alpha = 85.98 (2), beta = 79.72 (2), gamma = 79.95 (2)-degrees, V = 789.0 (4) angstrom 3, Z = 1, D(x) = 1.90 g cm-3, lambda(Mo K-alpha) = 0.71073 angstrom, mu = 19.01 cm-1, F(000) = 455, room temperature, R(F) = 0.049, wR(F) = 0.057 for 1382 unique reflections. The structure consists of layers of partially oxidized BEDT-TTF cations [BEDT-TTF = bis(ethylenedithio)tetrathiafulvalene] separated along the c direction by discrete, linear CuCl2- anions. Intermolecular S...S distances shorter than the sum of the van der Waals radii (3.6 angstrom) are found only between interstack BEDT-TTF molecules. Four-probe conductivity measurements indicate that the crystal is a semiconductor, with a relatively small bandgap of 45 meV. [GRAPHICS]
