A series of radical cation salts based on nonplanar DOET [(1,4-dioxanediyl-
2,3-dithio)ethylenedithiotetrathiafulvalene ] donor with the ReO4-, HSO4-,
FSO3- Hg2Br6-2, Hg2Cl6-2, NO3-, SiF5- anions has been synthesized. Crystal
structures and conducting properties have been studied. The first DOET salt
retaining metallic state down to 4 K has been found.
