Abstract

Conformations of flexible zwitterionic omega-pyridinium alkanoates (PBn) with n methylene units in the tether and their hydrates and hydrochlorides were investigated. Findings showed that conformation of flexible zwitterionic betaines is stabilized by the electrostatic interaction between the charged centers and hydrogen bonding. Linear molecules in crystals were arranged antiparallel with short intermolecular contacts between the N+ and COO- groups.
