Abstract :
The structural and physical properties of the title compounds (where P-S,S-DMEDT-TTF is pyrazino- S,S-dimethylethylenedithio-tetrahiafulvalene and EDO-S,S-DMEDT-TTF is ethylenedioxy-S,S-dimethylethylenedithio-tetrathiafulvalene) show that these crystals are 2D metals with unusual behaviour for temperatures lower than that of metal-insulator transition (<50 K).
