Halogenated Bis(methylthio)tetrathiafulvalenes as a Unique Donor System

Abstract

Abstract Chlorination, bromination and iodination of bis(methylthio)tetrathiafulvalene (BMT-TTF) produced mainly the dihalogenated products (BMT-TTFX2) with small amounts of the monohalogenated derivatives (BMT-TTFX). The molecular structures of BMT-TTFBr2 and BMT-TTFBr2•I3 have been determined, and the conductivities of CT-complexes and radical salts derived from BMT-TTFX2 have been measured.
