An organic superconductor, (TEA)(HEDO-TTF-dc) 2 ·2(H 2 C 2 O 4 ), coupled with strong hydrogen-bonding interactions

A new organic superconductor (TEA)(HEDO-TTF-dc) ·2(H C O ) (H EDO-TTF-dc = ethylenedioxy-tetrathiafulvalene dicarboxylic acids) with an onset of 4.0 K, was successfully obtained using oxalic acid and HEDO-TTF-dc anion donor. The crystal structure analysis indicated that strong π-π overlaps and very...

Description
Summary:A new organic superconductor (TEA)(HEDO-TTF-dc) ·2(H C O ) (H EDO-TTF-dc = ethylenedioxy-tetrathiafulvalene dicarboxylic acids) with an onset of 4.0 K, was successfully obtained using oxalic acid and HEDO-TTF-dc anion donor. The crystal structure analysis indicated that strong π-π overlaps and very strong intra- and inter-molecular hydrogen-bonding interactions exist between the HEDO-TTF-dc anion donors and oxalic acid molecules.
