The First Proton‐Conducting Metallic Ion‐Radical Salts

This is the authors' abstract. We don't add key points for this paper.

Any old ion? Two bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) radical salts with ion channels of stacked [18]crown-6 and Cat/H2O molecules (Cat=H3O+ or NH4+) are described. The structures contain alternating BEDT-TTF layers, [(Cat)M(C2O4)3]2− (M=Ga, Cr) layers, and the [18]crown-6 ion channels (see picture). The salts are metallic electrical conductors, and they show high protonic conductivity.
