Abstract
The structures of the six hydrogen-bonded 1:1 compounds of 4-methylquinoline with 2-chloro-4-nitrobenzoic acid, 2-chloro-5-nitrobenzoic acid, 2-chloro-6-nitrobenzoic acid, 3-chloro-2-nitrobenzoic acid, 4-chloro-2-nitrobenzoic acid and 5-chloro-2-nitrobenzoic acid have been determined at 185–190 K. In each crystal, the acid and base molecules are linked by a short hydrogen bond between a carboxy/carboxylate O atom and an N atom of the base.
