Abstract
The structures of two isomeric compounds of isoquinoline with 3-chloro-2-nitrobenzoic acid and 4-chloro-2-nitrobenzoic acid have been determined at 190 K. In each compound, the acid and base molecules are held together by a short hydrogen bond between a carboxy O atom and a base N atom. In the hydrogen-bonded unit of the former, the H atom is disordered over two positions, while in the latter, an acid–base interaction involving H-atom transfer occurs and the H atom is located at the N site.
