Solid-state structure and electronic states of hydrogen-bonded dimer of pyridyl-substituted tetrathiafulvalene salted with PF₆⁻

Abstract

Our results clarified uniqueness in hydrogen bonding TTFPy dimer in which proton in hydrogen bond was thermally fluctuated. In addition, the fluctuation was coupled with π-electronic systems of TTF moiety where electric dipole moment was amplified.
