Abstract

The radical cationic salt of methyl enedithiotetraselenafulvalene (MDT-TSF), shown in the picture was formed on its treatment with AuI₂-. The salt showed a superconducting transition at 4.5 K (onset) at ambient pressure. The crystal structure of the MDT-TSF cation is completely planar and stacked along its a-axis; the calculated overlap integral is five times greater in the intrastack compared to the interstack direction and the material is therefore quasi one-dimensional.
