Synthesis And Characterization Of Organic Superconductors

Abstract

The organic donor ethylenemethylenedithiotetrathiofulvalene (MET), a derivative of the bis(ethylenedithio)tetrathiofulvalene (BEDT-TTF or ET) organic donor, has been electrochemically oxidized with tetrabutylammonium salts of PFg‘ and CIO4" to form MET/PFg and MET/CIO4 crystals. The resulting crystals were or will be studied to determine crystal structure, electron spin resonance, and conductivity. X-ray crystallography was performed on 7 different crystals. Initial structure analysis consisted of Weissenberg and /or Precession X-ray analysis. These procedures yield information on crystal symmetry and lattice parameters.
