摘要：

The synthesis and electrochemical properties of several organometallic tetrathiafulvalene (TTF) dimers, whose redox units are held across -Hg-, -SiMe2-, or -PPh- links, are described. The extent of interaction between the TTF's in each dimer has been evaluated by cyclic voltammetry experiments and extended Huckel calculations. It appears to depend mainly on the nature of the bridging atom and the distances between the two redox centers. (TTF)2SiMe2 crystallizes in the orthorhombic system, space group Pnma, with a = 12.584(1) angstrom, b = 24.96(1) angstrom, c = 6.404(1) angstrom, and Z = 4.
