摘要：

(C10H8S8)2[Cd2I6], M(r) = 1755.60, triclinic, P1BAR, a = 9.067 (2), b = 10.515 (1), c = 12.441 (2) angstrom, alpha = 97.12 (1), beta = 103.43 (1), gamma = 106.13 (1)-degrees, V = 1085 (1) angstrom 3, Z = 1, D(x) = 2.69 g cm-3, lambda-(Mo K-alpha) = 0.71073 angstrom, mu = 59.6 cm-1, F(000) = 806, room temperature, R(F) = 0.051, wR = 0.061 for 2761 unique reflections. The structure consists of pairs of BEDT-TTF cations [BEDT-TTF = bis(ethylenedithio)tetra-thiafulvalene] with an interplanar separation of 3.53 angstrom and Cd2I62- anions formed by two CdI42- tetrahedra sharing one common edge. pi-pi molecular overlap exists within each pair of BEDT-TTF molecules, while different pairs are linked via S...S contacts, which are as short as 3.339 (3) angstrom.
