Abstract
A new molecular complex based on [60]fullerene, namely, (BMDT-TTF)·C60·2CS2 (1) (where BMDT-TTF is bis(methylenedithiotetrathiafulvalene)) was synthesized. The molecular and crystal structures of 1 were established by X-ray diffraction analysis. Complex 1 has a layered structure, layers of C60 molecules alternating with those formed by BMDT-TTF molecules and CS2 molecules located between them. In complex 1, there are short contacts between C60 and the donor molecules, which results in a changed BMDT-TTF geometry. The donor molecules in 1 form in addition short S...S contacts. The data of IR spectroscopy indicate that the charge transfer to the fullerene molecule is insignificant if at all present. The conductivity of a single crystal of 1 measured at ∼20 °C using a four-contact method is 2·10–5 (Ω cm)–1.
