Abstract
A new organic-inorganic salt formed by mixed-valence TTF chains and [Mo8O26]−4 is obtained by electrochemical oxidation of the donor in acetonitrile solution containing the polyanion. A unusual zigzag stacking of the donor molecules along the b-axis of the triclinic cell is observed, with close intrachain and interchain contacts through the sulpur atoms (the shortest S-S distances are about 3.5 Å). A semiconducting behavior has been observed with a conductivity σ ≈ 10−3 S.cm−1 at room temperature. The magnetic properties indicate that the compound is non magnetic.
