Abstract

The title compound, C6H7ClNO⁺·Cl^-, crystallizes in orthorhombic space group Pnma with both cations and anions lying on a mirror plane in the crystal. The C - Cl distance is 1.7289(6)Å, the C - N distance is 1.4590(8)Å, and the C - O distance is 1.3617(8)Å. Parallel molecules form stacks with interplanar spacing 3.1473(2)Å, but slipped by 1.97Å. The NH3⁺ substituent donates three intermolecular hydrogen bonds to chloride ions having N⋯Cl distances in the range 3.1514(6)-3.3019(2)Å, and the OH group donates an intermolecular hydrogen bond to chloride with O⋯Cl distance 3.0671(6)Å. The chloro substituent and OH group do not accept hydrogen bonds from NH or OH.
