Crystal structure and thermoelectric properties of an organic compound of tetrathiafulvalene (TTF) and iodine (I), TTF-I0.71, were investigated. From X-ray diffraction of TTF-I0.71 powder prepared by a solid state reaction, the superspace group of TTF-I0.71 was determined as C2/m(p0r)0s. The TTF-Ix thin films were also fabricated on a glass substrate. It was found that the actual composition x increased with film thickness, and reached to approximately 0.72 above 300 nm. The Seebeck coefficient and electrical conductivity of the films showed time-dependent change, due to the homogenization of iodine concentration in the film.
