Abstract

A new radical-cation salt β-(DOET)4CuBr4·PhCl (DOET = (1,4-dioxanediyl-2,3-dithio)ethylene-dithiotetrathiafulvalene) is synthesized by electrocrystallization in the dc mode (I = 0.12 μA), and its structure is studied. In the structure of the salt, the DOET radical cations are packed in layers parallel to ab. The average charge on DOET is equal to +0.5. The dioxane rings and ethylene groups of DOET, the tetrahedral CuBr 2−4 -anion, and the chlorobenzene molecules are each disordered over two positions with a 50% probability, and the chlorine atoms of chlorobenzene are disordered over four positions with a 25% probability. The salt has semiconducting properties (E a = 55 meV).
