New organic metal β-(DOET)2FSO3•H2O: synthesis and crystal structure

A. A. Bardin (a), A. I. Kotov (b), G. V. Shilov (b), and E. B. Yagubskii (b)

An organic metal β-(DOET)2FSO3•H2O based on a novel donor DOET (DOET is (1,4-dioxane-2,3-diyldithio)ethylenedithiotetrathiafulvalene) was synthesized and structurally characterized. Single crystals were prepared by electrochemical oxidation of DOET in the d.c. mode. The salt has a layered structure with the DOET1/2+ radical cation layers parallel to the ab plane. The FSO3 – anion is equiprobably disordered over two positions relative to the center of symmetry (1/2, 0, 0). The temperature behavior of conductivity is characteristic of metals in the temperature range from 293 down to 96 K; below 96 K, an increase in resistance is observed.
