Synthesis, crystal structure, and conducting properties of a new molecularconductor (DBTTF)(11)(TeCl6)(4)

The structure and conducting properties of a new radical cation salt of dib enzotetrathiafulvalene (DBTTF), viz, (DBTTF)(11)(TeCl6)(4) (1), were studie d. According to the X-ray diffraction data. the crystal of 1 contains six c rystallographically independent DBTTF radical cations alternating with stac ks of the (TeCl6)(2-) anions. At room temperature, the conductivity of the crystals is 15 S cm(-1) and it changes exponentially as the temperature dec reases. lt was found that an increase in the size of the anion in compounds of type 1 results in the appearance of interactions between the stacks and in an enhancement of the two-dimensional character of the conductivity.
