The title complex was synthesized by the reaction of copper(I) iodide and tetrakis(ethylthio)tetrathiafulvalene (TTC2-TTF) in acetonitrile under argon atmosphere. The new compound, [(CuI)2TTC2-TTF], crystallizes in the monoclinic system, space group P21/m with unit-cell dimensions a = 9.843(2), b = 12.946(2), c = 10.079(1) Å, β = 99.91(1)°, V = 1265.2(4) Å3, and Z = 2. It is a neutral 2 : 1 (metal/ligand) complex in which each metal ion is tetrahedrally coordinated by two bridging iodide ions and two sulfur atoms from TTC2-TTF to form coordination polymeric chains. The average Cu–I and Cu–S bond lengths are 2.601 and 2.369 Å, respectively. The complex was doped with iodine to afford [(CuI)2TTC2-TTF]I1.5 which exhibits a conductivity of 2 × 10−3 S cm−1 at 25 °C for a compacted pellet.
在氩气环境下,碘化铜(I)和四(乙硫基)四硫杂戊烯(TTC2-TTF)在乙腈中发生反应,合成了标题复合物。新化合物[(CuI)2TTC2-TTF]在单斜晶系中结晶,空间群为 P21/m,单位晶胞尺寸为 a = 9.843(2),b = 12.946(2),c = 10.079(1)埃,β = 99.91(1)°,V = 1265.2(4)埃3,Z = 2。它是一种 2:1(金属/配体)的中性复合物,其中每个金属离子都通过两个桥接碘离子和 TTC2-TTF 的两个硫原子进行四面体配位,形成配位聚合物链。Cu-I 和 Cu-S 键的平均长度分别为 2.601 和 2.369 Å。该复合物掺杂了碘,得到了[(CuI)2TTC2-TTF]I1.5,25 °C时,压实颗粒的电导率为 2 × 10-3 S cm-1。
