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.
