卤化铜(II)与过量的四硫富瓦烯(TTF)在不同溶剂中发生氧化还原反应，得到多种导电混合价络合物：(TTF) 2CuCl2 (粉末电导率在300 K下为14 S cm" 1)在甲醇中，(TT-F) 7 (CuCl2) 3 (10 S cm" 1)在乙腈中，(TTF) 5 (CuBr2) 3 (1.5 S cm" 1) 甲醇溶液、(TTF) 4 (CuBr2) 3 (0.3 S cm" 1) 四氢呋喃溶液和 (TTF) 6CuBr4 (14 S cm" 1) 乙腈溶液。电子自旋共振、红外和 X 射线光电子能谱研究表明，在每种化合物中，铜原子均处于 Cu1 态，TTF 部分带有磁化率表明不成对电子在 TTF 晶格上广泛离域。
The redox reaction of copper (II) halides with excess tetrathiafulvalene (TTF) yielded a variety of electroconductive mixed-valence complexes indifferent solvents:(TTF) 2CuCl2 (the powder electrical conductivity was 14 S cm" 1 at 300 K) inmethanol,(TT-F) 7 (CuCl2) 3 (10 S cm" 1) in acetonitrile,(TTF) 5 (CuBr2) 3 (1.5 S cm" 1) in methanol,(TTF) 4 (CuBr2) 3 (0.3 S cm" 1) intetrahydrofuran, and (TTF) 6CuBr4 (14 S cm" 1) in acetonitrile. Electron spin resonance, infrared, and X-ray photoelectron spectroscopic studies indicated that, in each compound, the copper atoms are in the Cu1 state and TTF moieties carry a fractional charge equally. The magnetic susceptibilities suggested that unpaired electrons are extensively delocalized over the TTF lattices.
