A new series of radical-cation salts based on asymmetrical ethylenedithiodimethyl-tetrathiafulvalene (EDTDM-TTF). Properties and crystal structure of (EDTDM-TTF)2PF6

Abstract

A new series of radical-cation salts with inorganic anions PF_6^–, Br^–, ClO_4^–, HgCl₃^–, I^– has been prepared by electrochemical oxidation of ethylenedithiodimethyltetrathiafulvalene (EDTDM-TTF); the electrical conductivity and crystal structure of one of them, (EDTDM-TTF)₂PF₆, are reported and the three-dimensional character of its arrangement is suggested.
