The refined crystal structure of stilbazolium derivatives was determined by neutron diffraction. The interatomic distances between the cation and the anion increased when the 4-position of the benzenesulfonate counteranion had a larger atom. The absorption coefficients of the 4-halobenzenesulfonate stilbazolium derivatives in the THz region became lower.
