The first molecular charge transfer salt containing proton channels

Abstract

We report the first molecular charge transfer salt containing channels of H3O+/H2O within its lattice; it is formulated β″-(BEDT-TTF)4[(H3O)Cr(C2O 4)3]2[(H3O)2(18-cro wn-6)]·5H2O [BEDT-TTF = bis(ethylenedithio)tetrathiafulvalene], deduced from the crystal structure and CC and C–S bond lengths and Raman stretching frequencies.
