A conducting thallium salt of 2,5‐dimethyl‐<i>N, N</i>′‐dicyanoquinone‐diimine, [2,5‐DMe‐DCNQI]₂Tl: Comparison with other related radical anion salts

Abstract

A radical anion salt based on thallium (see figure, where M = Tl) has been prepared. It is found to be the only such conducting compound, except the copper analogue, which shows a positive NMR knight shift indicating an electronic interaction between the central atom and the ligand. magnified image
