Observation of counterion effects and dimensionality reduction in single-crystal (EDO-TTF)2SbF6 with ultrafast electron diffraction

Abstract

Femtosecond electron diffraction is used to resolve structural dynamics in single-crystal (EDO-TTF)2XF6 (X = P, Sb). The retarded and lower-dimensional dynamics of the latter illustrate the dominant role of counterion motion in stabilizing electron transfer.
