摘要
The title compound, C5H5ClNO+.Cl-.H2O, shows typical features of pyridinium cations (i.e, wider angles at nitrogen and narrower angles at C-2 and C-6 than in unprotonated pyridines). Short C-Cl and C-O bonds may indicate mesomeric stabilization of the positive charge at the N atom. The extended structure involves classical hydrogen bonds of forms N-H ... Cl-, O-hydroxy-H ... O-water and O-water-H ... Cl-. Short Cl ... Cl contacts of 3.3460 (8)Angstrom are also observed. Secondary interactions link anions and cations to form a three-dimensional packing pattern.
