In each of the title isomeric compounds, C9H7.3N·C7H3.7ClNO4, (I), and C9H8N·C7H3ClNO4, (II), of iso-quinoline with 3-chloro-2-nitro-benzoic acid and 4-chloro-2-nitro-benzoic acid, the two components are linked by a short hydrogen bond between a base N atom and a carb-oxy O atom. In the hydrogen-bonded unit of (I), the H atom is disordered over two positions with N and O site occupancies of 0.30 (3) and 0.70 (3), respectively, while in (II), an acid-base inter-action involving H-atom transfer oc ...[more]
