2-Chloro-4-hy-droxy-anilinium chloride.

ABSTRACT: The title compound, C₆H₇ClNO⁺·Cl^-, crystallizes in ortho-rhom-bic 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 mol-ecules form stacks with inter-planar spacing 3.1473 (2) Å, but slipped by 1.97 Å. The NH₃ ⁺ substituent donates three inter-molecular 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 inter-molecular 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.
