摘要：

Two copper(I) complexes with tetrakis(ethylthio)tetrathiafulvalene (TTC2-TTF), [(CuCl)(2)TTC2-TTF] (1) and [(CuBr)(2)TTC2-TTF] (2), have been synthesized and characterized by spectroscopic and X-ray crystallographic methods. Both 1 and 2 are neutral 2:1 (metal/ligand) complexes in which each metal ion is coordinated in a distorted tetrahedral geometry to two bridging halide ions and two sulphur atoms from TTC2-TTF. The crystal of 1 has a two-dimensional structure in which TTC2-TTF molecules are connected between novel helical CuCl frames, while the crystal of 2 has a one-dimensional polymeric chain structure. The average Cu-Cl and Cu-S bond lengths are 2.282(2) and 2,405(2) Angstrom in 1 and Cu-Br and Cu-S bond lengths are 2,445(2) and 2,349(1) Angstrom in 2, respectively. Compounds 1 and 2 were doped with iodine to afford [(CuCl)(2)TTC2-TTF]I (3) and [(CuBr)(2)TTC2-TTF]I (4) which exhibit electrical conductivities of 6 x 10(-7) and 3 x 10(-7) S cm(-1), respectively, at 25 degrees C for compacted pellets.
