4-Meth­oxy­anilinium 2-carb­oxy-4,5-di­chloro­benzoate

G. Smith and U. D. Wermuth

Abstract: In the title salt C7H10NO+·C8H3Cl2O4- the benzene rings of the cation and anion are essentially parallel [inter-ring dihedral angle 4.8 (2)°]. In the anion the carb­oxy­lic acid and carboxyl­ate groups make dihedral angles of 19.0 (2) and 79.5 (2)°, respectively, with the benzene ring. Aminium N-H...O, carb­oxy­lic acid O-H...O and weak aromatic C-H...O hydrogen-bonding associations with carboxyl O-atom acceptors together with cation-anion [pi]-[pi] ring inter­actions [minimum ring centroid separation = 3.734 (3) Å] give rise to a sheet structure lying parallel to (001).
