Abstract :
A new ST-TTP donor TMEO-ST-TTP, where TMEO-ST-TTP is 2-[4,5-bis(methylthio)-1,3-diselenol-2-ylidene)-5-(4,5-ethylendioxy-l, 3-dithiol-2-ylidene)-l,3,4,6-tetrathiapentalene, has been prepared. It affords highly conducting PF6− and AsF6− salts retaining metallic conductivity down to 4.2 K, while the TCNQ complex and ClO4− salt are low conductive semiconductors. X-Ray structure analyses reveal that (TMEO-ST-TTP)(TCNQ)(PhCl) has a DA type mixed stack, and that the donor array of (TMEO-ST-TTP)2ClO4(DCE) in the conducting sheet resembles β-BEDT-TTF salts.
