Intercalation of bis(ethylenedithio)tetrathiafulvalene (ET) into iron oxychloride: a highly conducting low-dimensional system

Efforts to prepare new organic conducting materials have focused primarily on the preparation of new organic donors or modification of existing donors. Herein, we report the preparation and preliminary characterization of a new intercalation compound, FeOCl(ET){sub 1/4}, where ET = bis(ethylenedithio)tetrathiafluvalene. Structural and electronic studies show that the material contains stacks that are partially oxidized, resulting in high electrical conductivity due to the intercalated electron donors.
