Chiral Molecular Metals: Syntheses, Structures, and Properties of the AsF₆^- Salts of Racemic (±)-, (<i>R</i>)-, and (<i>S</i>)-Tetrathiafulvalene−Oxazoline Derivatives

Abstract

A metallic behavior characterizes a first complete series of 2:1 AsF6- mixed-valence chiral salts of (R)-, (S)-, and racemic (+/-)-tetrathiafulvalene methyl-oxazoline derivatives. The enhanced conductivity of the pure enantiomeric salts, when compared with that of the racemic one, is the likely consequence of the structural disorder observed in the latter.
