Pyridoxinium trichloroacetate

Abstract

In the title compound, C8H12NO3+·C2Cl3O2−, the –CH2OH groups are twisted out of the plane of the pyridine ring. There is an intramolecular hydrogen bond between the phenol OH and the adjacent –CH2OH group with an S(6) motif. Closed R24(16) rings are observed around the inversion centres of the unit cell as a result of N—H...O and O—H...O interactions. Two zigzag chain C22(11) motifs are also formed by the hydrogen‐bonding interactions of the cations and the anions.
