Cj. Gomezgarcia et al., AN ORGANIC-INORGANIC SALT CONTAINING MIXED-VALENCE TTF CHAINS AND THEMOLECULAR-METAL OXIDE CLUSTER [MO8O26]-4 - PRELIMINARY SPECTROSCOPIC,CONDUCTING AND MAGNETIC-PROPERTIES OF THE COMPOUND (TTF)7MO8O26, Synthetic metals, 56(1), 1993, pp. 1787-1790
A new organic-inorganic salt formed by mixed-valence TTF chains and [M
o8O26]-4 is obtained by electrochemical oxidation of the donor in acet
onitrile solution containing the polyanion. A unusual zigzag stacking
of the donor molecules along the b-axis of the triclinic cell is obser
ved, with close intrachain and interchain contacts through the sulphur
atoms (the shortest S-S distances are about 3.5 angstrom). A semicond
ucting behavior has been observed with a conductivity sigma = 10(-3) S
.cm-1 at room temperature. The magnetic properties indicate that the c
ompound is non magnetic.
