(E)-2-[2-(3-Nitrophenyl)ethenyl]quinolin-8-ol

In the title compound, C17H12N2O3, the mean planes of the benzene ring and the quinoline moiety are inclined to one another by 11.0 (1)°. The nitro substituent is twisted at an angle of 7.9 (2)° with respect to the attached benzene ring. Intramolecular O—H...N and C—H...N hydrogen bonds occur. The crystal is constructed of molecular stacks without involvement of π-stacking interactions, but showing interstack association via O—H...O and C—H...O hydrogen bonding. Thus, the supramolecular architecture of the crystal results from stacked molecules stabilized by hydrogen bonding between the stacks.
