ResumoThe structure of histidine hydrochloride monohydrate has been refined by three-dimensional least-squares methods.The amino acid part of the molecule is in the zwitter ion form; the imidazole ring is positively charged.The distances in the imidazole ring, combined with some previous results, are satisfactorily interpreted with the valence bond theory, and imply a carbon-nitrogen double-bond distance of 1.265 /~.All available hydrogen atoms form hydrogen bonds.
