Abstract

In the structure of the hydrated 1:1 compound of 4-chloro-aniline with l-tartaric acid, C6H7ClN+·C4H5O6 -·H2O, determined at 130 K, the asymmetric unit comprises two 4-chloro-anilinium cations, two hydrogen tartrate anions and two water mol-ecules of solvation, and forms a two-dimensional duplex substructure comprising head-to-tail C 1 1(7) hydrogen-bonded hydrogen tartrate anions and water mol-ecules. The π-associated 4-chloro-anilinium cation pairs [ring centroid separation = 3.576 (4) Å; inter-ring dihedral angle = 0.5 (1)°] are accommodated within the channels of the substructure and are hydrogen-bonded to it peripherally. © International Union of Crystallography 2007.
